Can't compile gnome-libs-0.27

[Peter Petrakis <PeterPan wn net>]

I'm having some trouble compiling the above on RH 5.1 Alpha. rpm says when
 I do a rebuild.

checking whether to enable maintainer-specific portions of Makefiles... no
checking for pthread_create in -lpthread... yes
checking for gtk-config... /usr/local/bin/gtk-config
checking for GTK - version >= 1.1.1... no
*** Could not run GTK test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GTK was incorrectly installed
*** or that you have moved GTK since it was installed. In the latter case, you
*** may want to edit the gtk-config script: /usr/local/bin/gtk-config
configure: error: GTK not installed
Bad exit status from /var/tmp/rpm-tmp.41511 (%build)

I have gtk+-1.0.1-3 & 1.1.1-1 installed along with glib 1.0.1-3 & 1.1.2-1 .
No devel libs installed and all errata. & updates applied .
