Yes this is the way to go.  Never overwrite your system packages.  Even
though GTK+ is supposed to be binary compatible between minor versions,
you could and probably would break things.  Even if you didn't, the next
time you do a yum update, if there are any GTK+ updates, they will
overwrite your custom changes.

So yes.  When installing GTK+ from source, always install to a
non-system prefix (/usr/local, or /opt) and use environment variables to
build against it and run programs.  A bit of a pain, true, but less pain
than breaking your system, like the other poster on this list did when
he removed GTK2 in an attempt to get GTK3 to compile and install on his
ubuntu box!  Completely broke his OS and he will probably have to
re-install.
