That should have been installed with the gtk-devel packages with your
distro.  If it's working then
  pkg-config --modversion gtk+-2.0
will print your version of GTK.

That's just standard autoconf output where it tries to figure out everything
about your development environment.  It may be safely ignored.

That bit is optional, and the test seems to get confused by the current
output from gcc --version, so just ignore it for now.

Are you installing GTK from source?  If not, which distro are you using as
pkg-config must be a dependency of gtk-devel (and most of the other -devel
packages).  If you are installing from source, please reconsider.  It's not
for the faint of heart, or the inexperienced.

If you have been developing with GTK already, how have you managed to link
it in?

It acts like a shared library by default, so the end users must have it
installed.  You could try linking to the static library, then they wouldn't
need to install ROX-CLib, but I've not tried that to see if it works.
