trouble with libpython

Hello,
I got some trouble installing blender for linux.
I downloaded blender-2.47-linux-glibc236-py25-i386.tar.bz2 and I want to install it on an old version of Red Hat equipped with Python 2.2, so I installed python 2.5, typing

Python -V

I get

Python 2.5

so I guess Python is correctly installed.
When I launch blender I’ve this error message

./blender: error while loading shared libraries: libpython2.5.so.1.0: cannot open 
shared object file: No such file or directory

In /usr/lib I didn’t find any libpython*, I typed

locate libpython

an I just found /usr/local/lib/python2.5/config/libpython2.5.a.

How do I get libpython2.5.so.1.0? Did I get something wrong during Python installation?

Another question:
what’s the difference between
blender-2.47-linux-glibc236-py25-i386.tar.bz2
blender-2.47-linux-glibc236-py25-i386-static.tar.bz2

Thanks in advance for your reply!

I have the same problem with OpenSuse 11.1 and blender 2.48a
With Opensuse 11.0 it worked just fine
