Instalation of GTK+ 2.6 alongside GTK+ 2.4

[Derrick J Houy <djhouy paw za org>]

I run on Fedrora Core 3 which has GTK+ 2.4.13 installed. I want to 
continue to build my apps against the standard packages included in FC3, 
but also need to fix some bugs which allow the apps to work with GTK+ 2.6.7.

Can anyone help me with the best setup to easily allow building against 
the newer versions, without having to upgrade the current system version.

Thanks in advance...
