There appear to be two paths to running SublimeText2 on FreeBSD.
A binary package could be created. Create a local port on a build box. After some rounds of compiling, installing, and testing, one could 'make package' and distribute the tarball.
The Linux emulator for FreeBSD (linux-base-f10) is out of date, but only one version (see below) behind what ST2 needs. The author could build with an older version of libc/libstdc++, or the linux-base-f10 maintainers could update the libraries.
$ ldd sublime_text
sublime_text: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by sublime_text)
sublime_text: /lib/libc.so.6: version `GLIBC_2.11' not found (required by sublime_text)
sublime_text: exit status 1
$ strings /compat/linux/usr/lib/libstdc++.so.6.0.10 | grep GLIBCXX
Either solution shouldn't be too ambitious, though in my opinion, former would be the best solution since it follows the current idiom.
Either way, it'd make this licensed user a bit happier.
