[Mono-osx] Redistributable Mac OSX app without mono using mkbundle2

Preliminary question: why don't you use the NAnt tasks (<mkappl/> and
<mkbundle/>) available in Monobjc ? They are supposed to do all the dirty
stuff for you (native library gathering, relocation, remapping, etc.). There
is even a tutorial for that:

For the GLib problem, this is a regression from 2.6.3. The pkg-config file
for Mono is incomplete, as the 2.6 branch still depends on GLib. You can
quick-fix this issue by copying the "mono.pc" file from the 2.6.3
