Problem with compilling XFCE

[Karol]

Today I download files from CVS (xfce-devel/xfce4). I tried compile it
using RedHat 8.0. Unfortunatelly I have installed two RPM's one with
glib-2.0 and another with glib glib-1.2. Every time I try to run script
"configure" I got error that my glib version is lower than 2.0
Pkg-config see only the older library.

Is there any solution for my problem?

Thanks
