FYI, I found one additional wrinkle compiling on fedora. Autoconf isn't properly checking for the presence&correct version of package "pango-devel" and this is causing a failure in ./configure with a message that doesn't suggest a missing package:

checking for GTK2... configure: error: Package requirements (gtk+-2.0 >= 2.0.3) were not met:

Package pango was not found in the pkg-config search path.
Perhaps you should add the directory containing `pango.pc'
to the PKG_CONFIG_PATH environment variable
Package 'pango', required by 'GDK', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GTK2_CFLAGS
and GTK2_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Installing pango-devel-1.26.2-1.fc12.x86_64 allows ./configure to built the Makefile.
