Help on Glib and pango installations.

[nkb <nkb pacific net sg>]

Hi.
Beginner's question.
I'm trying to install gtk2.2.3. I downloaded and installed glib-2.2.3. 
When installing pango-1.2.5, it reports an error that says Glib 2.1.3 or 
better is required. But I just installed successfully [without error] my 
glib 2.2.3! So, how do I check and confirm that my glib was installed 
successfully? Or how do I tell pango that I've glib 2.2.3 installed?
Any pointers will be helpful.

Thanks.
