I cd'd to atk-1.0.3, ./configure'd, make'd, and make installed'd.
Same to glib-2.0.7.

Unfortanately, when I ./configure'd gtk+-2.4.9, it gave the following...

[root@localhost gtk+-2.4.9]# ./configure
checking for a BSD-compatible install... /usr/bin/install -c
...
...
...
configure: error: Library requirements (glib-2.0 >= 2.4.0 atk >= 1.0.1 pango >= 1.4.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
[root@localhost gtk+-2.4.9]#

[root@localhost gtk+-2.4.9]# echo $PKG_CONFIG_PATH
/root/glib-2.0.7
[root@localhost gtk+-2.4.9]#

Any help is appreciated! ^.^ Ty.
