It doesn't have anything to do specifically with OSX. It's any version of libtool. IIRC, if we ship with glibtool-2.x, that version's macros will be added to the m4 directory. If we then do an 'autoreconf -fvi' in the directory, depending on the version of glibtool on the system, it's not deterministic which version of the m4 macros will be used (packaged versus system)... but the system's glibtool will always be used...
