My local MacPorts repo for ports to submit to MacPorts
Just wait until the main MacPorts project commits them, if they haven't yet. If you really can't wait, you can always clone this repo and then add it to your sources.conf file.
Some of these ports are copied from the portfiles in the main version of MacPorts. If you use these, you could end up with broken portfiles shadowing the good ones. See bug 36951 on the MacPorts Trac for further information.
I have a portfile pointing to this repo; the only reason for its existence is to install a bunch of dependencies.
