No doubt you are running into same problem that is described here: http://stackoverflow.com/questions/12553057/compile-python-2-7-3-from-source-on-a-system-with-python-2-7-already

The problem is, that on most Unix systems (with the notable exception of Mac OS X), the path to shared libraries is not an absolute path.  So, if you install Python in a non-standard location, which is the right thing to do so as not to interfere with a system Python of the same version, you will need to configure in the path to the shared library or supply it via an environment variable at run time, like LD_LIBRARY_PATH.  You may be better off avoiding --enable-shared; it's easy to run into problems like this with it.
