Ugh. The problem is that buildlink3 is turning
     ../glib/.libs/libglib-2.0.dylib
into
     -L../glib/.libs -lglib-2
because it thinks the ".0" is part of a shared library version rather  
than being part of the library name. (And in fact, the complete library  
name is libglib-2.0.200.3.dylib, and there's really no way it can know  
that the ".0" is part of the library name and the ".200.3" isn't.)

I got glib2 to build by using the attached patch to  
pkgsrc/mk/buildlink3/gen-transform.sh, but I haven't tried building  
anything else to see if it breaks anything yet (or if anything breaks  
that this patch doesn't cover). It's also kind of a gross hack.

Another possibility might be to make libtool or something rename shared  
libraries on OS X so we'd have libglib-2_0 instead of libglib-2.0. That  
could also be gross though...

That's harmless. glib actually checks whether or not gcc supports the  
"-pthreads" flag, but OS X's gcc prints the warning and then just  
ignores it rather than exiting with an error code, so glib thinks it  
supports the flag and always passes it after that.
