[J. W. Ballantine]

When building gobject-introspection on a current ports tree,
it fails with:

I've rebuilt the python tree and glib20 and the version of gcc
is gcc version 4.2.1 20070831 patched [FreeBSD].

Since this port is integral to the gnome package, what do I need to
do to get it built?

Thanks
