Can't install dbg and normal version at the same time

[Nikratio]

It seems that installing either version first purges the other version. Reproduced with 0.5.28:

$ python-dbg setup.py install --user
$ (cd /; python -c 'import pycryptopp')
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/nikratio/.local/lib/python2.6/site-packages/pycryptopp-0.5.28-py2.6-linux-i686.egg/pycryptopp/__init__.py", line 17, in <module>
    import _pycryptopp
ImportError: No module named _pycryptopp
$ (cd /; python-dbg -c 'import pycryptopp')
