I was hoping to use a pre-compiled library. I'm trying to stick to
releases as much as possible.
Hmm, actually, if I run "otool -L libclang.dylib" it prints:
@rpath/libclang.dylib (compatibility version 1.0.0, current version 0.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version
Which seems to indicate that it only depends on the C++ standard library
and the C system library (or what else is in libSystem). Those
dependencies are easy enough to satisfy :)

Ok, I see.

I have a virtual machine running Ubuntu 6.x just for this :)
