[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.
