fedora is out to get me

[<jessopb adelphia net>]

checking for GLIB - version >= 2.5.7...
*** 'pkg-config --modversion glib-2.0' returned 2.6.4, but GLIB (2.4.8)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system.
*** If pkg-config was wrong, set the environment variable PKG_CONFIG_PATH
*** to point to the correct configuration files
no
configure: error:
*** GLIB 2.5.7 or better is required. The latest version of
*** GLIB is always available from ftp://ftp.gtk.org/. If GLIB is installed
*** but not in the same location as pkg-config add the location of the file
*** glib-2.0.pc to the environment variable PKG_CONFIG_PATH.

I've installed and reinstalled glib and pkg-config and other things the installation guide mentions.

Why is fedora's gtk called gtk-2.0 instead of gtk+-2.0?

atk keeps stalling on configure.  this was the last error I got.  How do I remove the old glib?

THanks
