What Linux distribution is this on? I tested these changes on quite a few 
different distributions and the shared object in 
python${_CURRENT_VERSION}/config was a symlink to python${_CURRENT_VERSION}.so 
in the /usr/lib directory. Does your installation not have 
/usr/lib[64]/libpython2.5.so?

Quite a few Linux distributions do not have the symlink in 
python${_CURRENT_VERSION}/config, whereas all the ones I came across had it in 
/usr/lib. So this would lead to link errors as only the static lib would be 
found, and that cannot be used on x86_64 for example.

If you could provide more details then I will look into this further (I 
committed the change in response to a bug report, and numerous reports I had 
from users who had trouble linking to Python on 64 bit platforms).
