Good news, we are getting closer to understanding what to do.
This in from Ned.  I will continue after the message:

Installing a python.org Python (/usr/local/bin/python*) is independent 
of and does not interfere with use of the Apple-supplied system Pythons 
(/usr/bin/python*).  Apple does ship various third-party Python packages 
("distributions") with its system Python, like numpy, but they tend to 
be old and outdated versions and there are a few Apple-only packages.  
But, should that issue arise, that can be resolved by choosing the right 
path (/usr/local/bin vs /usr/bin) or removing /usr/local/bin from $PATH.

The thing is the original message in this thread had this:

But ... I just did what I should have done earlier: googled for that 
message.  And I find that the message is coming from a py2app-built 
application (and it seems I answered the question 3 years ago!):

http://stackoverflow.com/questions/10184974/py2app-is-not-copying-the-pyt
hon-framework-to-the-new-app-while-using-virutalenv

The py2app glue code could be looking for Pythons in various spots 
including the system Python.  So, let's make sure the system Python is 
still working.  On the most up-to-date 10.7 Lion system (10.7.5), typing 
the following two commands should give results the same as those shown 
(->):

/usr/bin/python2.7 -c 'import sys;print(sys.version)'
- -> 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) 
- -> [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)]

/usr/bin/python2.7 -c 'import numpy;print(numpy.__file__)'
- -> 
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/pytho
n/numpy/__init__.py

If not, then it really may be necessary to restore system files which, 
as I noted before, is most safely and accurately done by following 
Apple's directions to restore the system from the recovery partition and 
a good backup of user files.

So please type

/usr/bin/python2.7 -c 'import sys;print(sys.version)'

and tell me what you get as an answer.

Then type

/usr/bin/python2.7 -c 'import numpy;print(numpy.__file__)'

and again tell me what you get.

But if it isn't as Ned expects, then you may have to go back to
your backups.
