That's correct. Funny you should ask, I've been working today on
updating those libraries to newer versions.

It is not a problem, but it is not possible to do this on stock redhat
8.0 (without a lot of work), the glib and gtk packages that are needed
by gtkmm 2.2 are newer than the ones provided in 8.0. RedHat 9 does not
have that problem. 

This is the error from the configure process (for gtkmm 2.2.3):

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... Requested 'glib-2.0 >= 2.2.0' but version of
GLib is 2.0.6

And to answer your next question, no, I'm not going to try upgrading
glib in 8.0 to a newer version :-) That sort of change usually triggers
a very long cascade of upgrades due to dependencies...

If you remove the 1.2 package you would need to also remove the
applications that depend on it to keep the rpm database in good shape.
