You have to lookout for the Summary:

--------- Summary --------------
       python: /usr
           uses --with-python=<dir> to find libpython.so
       xmlada: with_xmlada
           uses ADA_PROJECT_PATH to find xmlada.gpr

Python is activated when libpython.so is found. Actually it is 
lib/libpython.so and include/python/ which is needed.

Looks like your python is incompatible with your glibc.

De-install python - it's incompatible anyway. Or 
try --with-python=/some/where/bous - If I remember right when there is 
no /some/where/bous/lib/libpython.so then python is deactivated. The messages 
are misleading in that point. I remember trying --with-python=/usr/lib and 
being surprised that python was not included.
