Installing gtkmm from the sources
 

Hi!
I'm trying to install gtkmm packages (to develop GTK++ applications using C++), but while running the configure script of the gtkmm-2.2.28, appears this message:

checking for sigc++-1.2 >= 1.2.0 glib-2.0 >= 2.2.0 gobject-2.0 >= 2.2.0 gmodule-2.0 >= 2.2.0... Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' found

I used "locate glib-2.0.pc" but It didn't found anything. However, I thingk GTK and gnome is installed (I'm running Mandrake 9.2, and using Gnome-2.4). A similar message appeared before, saying "No package 'sigc`-1.2' found" but I added /usr/local/lib/pkg-config/ to PKG_CONFIG_PATH env variable, and it's solved. I need to do something similar?
Thanks!! :)
