You may get some clues by starting python as

/path/to/python/python2.7 -vv

which will provide the details of attempts to import:

[root@vsds4 log]# python2.7 -vv
# installing zipimport hook
import zipimport # builtin
# installed zipimport hook
# trying /usr/local/lib/python2.7/site.so
# trying /usr/local/lib/python2.7/sitemodule.so
# trying /usr/local/lib/python2.7/site.py
# /usr/local/lib/python2.7/site.pyc matches /usr/local/lib/python2.7/site.py
import site # precompiled from /usr/local/lib/python2.7/site.pyc
# trying /usr/local/lib/python2.7/os.so
# trying /usr/local/lib/python2.7/osmodule.so
# trying /usr/local/lib/python2.7/os.py
# /usr/local/lib/python2.7/os.pyc matches /usr/local/lib/python2.7/os.py
import os # precompiled from /usr/local/lib/python2.7/os.pyc
...
