FreeBSD and Shoes
We can support Shoes on FreeBSD 11.1 (very new bsd). But There are trade offs. and Bewares.
Shoes 3.3.4 users can package and app to run on FreeBSD and it will work if the end user has some dependencies already installed. There is no rational reason to expect your end users will have done that. They can do a pkg info gtk3 and there is gtk3 port available then they can do pkg install gtk3 Not Shoes thing to do just to try out an app but it's the only way. It's also the case that freebsd users are sophisticated enough to figure out what is missing.
Shoes does not have port package for bsd for the same reason it does not have a .deb or .rpm installer for Linux -- too many authorities about what to do, all different and too little time.
Only freebsd users think this is simple. It isn't, but you can get it done. You need to install some packages (ports in their lingo)
You need to install the emulators/virtualbox-ose-additions instead of the Guest Additions ISO
emulators/virtualbox-ose-additions does not support Shared Folders. I mount an nfs export from the VB host machihne. My /etc/fstab entry has the line(s) at the end
# mount nfs
bronco:/Projects /home/ccoupe/Projects nfs rw 0 0
That requires a /etc/hosts entry for bronco was setup first mine looks like
::1 localhost localhost.local
127.0.0.1 localhost localhost.local
127.0.0.1 flaco flaco.local
192.168.1.2 bronco
...
The Virtualbox host is 'bronco' at 192.168.1.2. The freebsd guest is 'flaco' 127.0.0.1 means it does hot have regular IP number - it can only reached from the host via domain sockets. This is a meaningful distinction.
I want to ssh from bronco into the freebsd VM flaco - named after Flaco Jimenez I did pkg install sshd and set the /etc/ssh/sshd_config to look like

It works for me in my situation: I want to ssh login even if X11 is not started. I chose to use port forwarding -- $ ssh -p 3022 ccoupe@127.0.0.1 from bronco (the VB host). We need a port mapping from port 3022 to VM port 22 and we do this using the Virtual-box Settings (Network -> Advanced-> Port Forward for on the freebsd guest.
I chose to install Mate for a window manager and once it's all debugged then you install slim if you want to boot to a graphical login screen (GDM). I don't - yet. startx will be fine. Configure as needed.
In no particular order, you'll want to pkg install git, makeself, vim, devel/ruby-gems, devel/rubygem-rake, databases/ruby-gdbm, xorg, and many more.
Although I don't need a Loose Shoes It's something I might want if freebsd was the main machine. Tight shoes has it's ruby in /opt and we can use that for Loose Shoes. I choose to set bash as the default
Now, if you want build Shoes from source on your FreeBSD box (or VM) - which you probably want to do then there is another rule or two or three. First rule - you'll want two rubies - Your system ruby and the one you package up with Shoes. So install a system ruby. sudo pkg install ruby which hints that you should pkg install devel/ruby-gems and pkg install rubygem-rake and pkg install databases/ruby-gdbm. Take the hints! Do it.
cd into the directory with your Shoes source (from git clone).
$ cd Projects/shoes3
$ rake -T

$We have a choice 'freebsd' and 'minbsd'. minbsd links against the system ruby and uses gems in that Ruby. This is a loose Shoes. Odds are high it's not built for redistribution. Loose Shoes also uses symlinks back into the source source tree so there is less copying. It also includes symbols. Perfect for playing around and debugging C. Let's build that first.
rake bsd:setup:minbsd
rake
Assuming it doesn't error out, this creates a minbsd directory, so ./minbsd/shoes is what to type to try it out. If you're following these instructions you'll notice that nothing useful is displayed. Alt-/ brings up the console which informs us the several gems failed to load. Easy solution, get those gems installed. If you like one-liners

#Now ./minbsd/shoes does work. It would be a good idea to take a look inside the minbsd directory and subdirectories to see how every thing is put together.
A couple of notes: My shoes source is NFS mounted and writing to NFS is slow. I direct where to place that minbsd directory by setting a shell environment variable.export NFS_ALTP=/usr/home/ccoupe/build/ That trailing slash is required. That's not a network place so builds are faster for me.
