Incompatibility of libraries

Hi,
I'm working with ROOT 5.22/00d (branches/v5-22-00-patches_at_29532, May 19 2010) on Linux 2.6.18-194.32.1.el5 2011 x86_64 x86_64 x86_64 GNU/Linux

I have a conflict between libraries that I cannot solve. Specifically I have the following two libraries, which (are supposed to) have absolutely no dependence between each other: -SpecialTools (which contains the class PhysicsProcess) -MEPATNtuple (which contains the class METree)

I can load the library containing the PhysicsProcess class and works just fine
root [0] gSystem->Load("../../lib/slc5_ia32_gcc43/libTAMUWWSpecialTools.so")
(int)0

root [1] PhysicsProcess * proc
root [2]

I can restart root and load the library containing the class METree and works fine as well
root [0] gSystem->Load("../../lib/slc5_ia32_gcc434/libTAMUWWMEPATNtuple.so")
(int)0

root [1] METree * me
root [2]

But when I load both of them I can only see the first library's classes
(true regardless of the order in which the libraries are loaded)

root [0]
gSystem->Load("../../lib/slc5_ia32_gcc434/libTAMUWWSpecialTools.so")
(int)0

root [1] PhysicsProcess * proc
root [2] gSystem->Load("../../lib/slc5_ia32_gcc434/libTAMUWWMEPATNtuple.so")
(int)0

root [3] METree * me
Error: Symbol METree is not defined in current scope (tmpfile):1: Error: Symbol me is not defined in current scope (tmpfile):1:
(const int)0

*** Interpreter error recovered ***
root [4] PhysicsProcess * proc
root [5]

So my question is very general, giving a conflict between libraries how can I start debugging where in the libraries my problem is at ? If there is an incompatibility between these libraries how can I pinpoint the source of that error ?

Thanks,
