gtk+-2?

[Neal D. Becker]

I am trying to build cycling-0.3.1.  I have fedora with everything, all
updates, and lots of extras.

configure fails here:
checking for gtk+-2.0 gdk-2.0... Package gtk+-2.0 was not found in the
pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found

I'm not familiar with gtk+.  rpm tells me I have gtk+-devel-1.2.10-28.1.  I
guess that's gtk+-1?  Can I find a gtk+-2 for fedora, and why doesn't
fedora have it (gtk+ website indicates gtk+-2 is not new).
