Error compiling gnome-core HEAD

["Joshua R. Odom" <jrodom stic net>]

While trying to compile gnome-core HEAD using the latest snapshot
packages from Ximian, I get the following set of errors:

I am using Red Hat 7.2 and other GNOME 2.0 apps such as nautilus have
compiled without error so everything appears to be installed properly...

Thanks in advance,
