gobject-introspection fails to on PowerPC mac : incompatible cpu-subtype for libffi.6.dylib

[RivetBenoit (Benoit Rivet)]

I tried to compile texlive on an old G3 iBook with Mac OS X.4. Surprisingly, most dependencies do compile, except for gobject-introspection, kerberos5 and ports depending on them.

The configuration of gobject-introspection does not reveal any problem, but while building gobject-introspection, the build fails with the following error :

:info:build     mod = imp.load_module(name, open(realpath), realpath, (extension, 'rb', 3))
:info:build ImportError: dlopen(./.libs/_giscanner.so, 2): Library not loaded: /opt/local/lib/libffi.6.dylib
:info:build   Referenced from: /opt/local/lib/libgio-2.0.0.dylib
:info:build   Reason: no suitable image found.  Did find:
:info:build 	/opt/local/lib/libffi.6.dylib: incompatible cpu-subtype

I tried to install an older version of gobject-introspection and had the same error (maybe I did not try an old enough version). Is there any workaround or is gobject-introspection definitely not meant to be compiled on Power PC hardware ?
