upgrade to gtk 2.2.2 question

[Markus Jais <markusjais yahoo de>]

hello

I have already installed gtk 2.0 and older versions of atk, glib and
pango

now I want to upgrade to gtk 2.2.2

do I have to uninstall the older versions first ??
how can I do this ??
they are no rpms and a 
$ make uninstall
is not possible because of missing directories where gtk2.0 was
compiled.

do I just have to remove everything by hand from the
/usr/local/lib 
directory ?

any hints welcome

thanks in advance

Markus
