Mitch, thanks! Following your setup worked perfectly.

glib did complain that $PREFIX/share/aclocal didn't exist, so I created 
the empty directory and then everything went smoothly, with GIMP and 
glib both writing ".m4" files to the aclocal directory. From curiosity, 
why didn't babl and GEGL also write ".m4" files?

In case anyone else is running Gentoo, the path (at least for a pure 
64-bit build) is "/usr/lib/gio/modules".

For the next person who encounters this problem, maybe a link to Mitch's 
post could be added to 
http://wiki.gimp.org/wiki/Hacking:Problems_and_solutions#GIMP_build_fails_for_missing_BABL_function?
