Problem porting gtk from gnome1 to gnome2 - pygtk-2.0?

[Thomas Frayne <TomFrayne sjpc org>]

Package gtk2 is on my Redhat 8.0 system, but pkg-config does not find
it.  Is there a .pc.in file somewhere?  Do I need to upgrade gtk2 or
pkg-config? Is pygtk-2.0 the package I need in the pkg-config call?

I am working on porting gnucash from gnome1 to gnome2, and have not been
able to determine the mapping from then gnome1 gtk package names to the
gnome2 names.

Below are the results of some related searches.

Package gtk2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk2.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk2' found
