[CentOS] pgadmin and Centos 5?

I've been fighting to get the latest source of pgadmin compiled on Centos 5 64-bit.

I obtained gnu-c++ (so it was happy with g++). It then complained about wxWidgets, so I obtained the source for that, compiled and installed, and ./configure for pgadmin saw wxWidgets and was happy with that. Go to make...

It complains that some header file is missing. A google search reveals limited answers, but the same couple of searches reveal the wxwidgets modules need to be installed. What are these modules that are needed for pgadmin? I've found plenty of modules when performing a google search of wxwidgets, such as python, etc.

Thanks for any help.
