md5sum errors when installing conda

[yangl1996]

When running miniconda-installer in FreeBSD shell, I get

md5sum: -: No such file or directory

I figured that FreeBSD's md5 no longer takes -. A workaround (as indicated here) is to run miniconda-installer once in FreeBSD shell so that it downloads the actual installer (Miniconda3-latest-Linux-x86_64.sh on my end), and then exit the installer, run conda-shell to go into a Linux shell, and finally run the installer directly (./Miniconda3-latest-Linux-x86_64.sh).

Instead of symlinking freebsd's md5sum I used linux's md5sum
pkg install coreutils
and then opened the sh script (for me it was in my ~)
and found this section:

# verify the MD5 sum of the tarball appended to this header
MD5=$(extract_range "${boundary0}" "${boundary2}" | gmd5sum -)
if ! echo "$MD5" | grep e713900ff53aea39b34b9da97d264ec2 >/dev/null; then
    printf "WARNING: md5sum mismatch of tar archive\\n" >&2
    printf "expected: e713900ff53aea39b34b9da97d264ec2\\n" >&2
    printf "     got: %s\\n" "$MD5" >&2
fi

All I had to do was instead of md5sum,
make it gmd5sum
and presto. BSD md5sum doesn't like their usage of - for some reason, but whatever.
