gdk_imlib.h missing?

[d rose salford ac uk]

I've finally decided I need to start compiling stuff from
source since quite a few of the gnome apps don't come with
rpms suitable for the PPC platform...

I _thought_ I'd downloaded and installed all the necessary
devel rpms, but whenever I try to compile stuff it always
chokes because "gdk_imlib.h" doesn't exist.

Anybody know which package this resides in (I must have
missed one) or can I pick it up from elsewhere?
