pygobject-2.14.2 on mac osx

I'm trying to build pygobject on osx 10.4 using gcc 4.0.1 after  
building:
cairo-1.6.4
pango-1.21.3
gtk+-2.12.2
glib-2.16.4
atk-1.22.0

I had to edit libtool to remove the ${wl} symbol before -undefined  
dynamic_lookup, it was causing a syntax error with gcc.
I also had to force -export-symbols-list .libs/_gobject- 
symbols.expsym  since -export-symbols-regex is not supported.

I'm getting the following error:

/bin/sh ../libtool --mode=link gcc  -g -O2 -Wall -fno-strict-aliasing
