[vtkusers] Empty PYTHONPATH while installing VTK on Mac OS Mountain Lion

[benoitd]

I am trying to install the latest GIT distribution of VTK on the latest Mac
OS X Mountain Lion (10.8.2), and I have a strange error. It compiles
perfectly well, but when I install it, I get a PYTHONPATH error. If seems
that the installer thinks my PYTHONPATH environment variable is empty, but
it rather contains: 

export
PYTHONPATH=/usr/local/lib/python2.7/site-packages:/Library/Python/2.7/site-packages:/TK/VTK/Wrapping/Python:/TK/VTK/Wrapping/Python/vtk:/TK/VTK/bin 

The error message I get is: 

----------------------------- 

-- Up-to-date: /usr/local/include/vtk-6.0/vtkPython.h 
-- Up-to-date: /usr/local/include/vtk-6.0/vtkPythonConfigure.h 
-- Up-to-date: /usr/local/include/vtk-6.0/vtkWrappingPythonModule.h 
running cd "/tk/VTK/Wrapping/Python" && /usr/bin/python setup.py install
--prefix="/usr/local"  2>&1 
running install 
Checking .pth file support in /usr/local/lib/python2.7/site-packages/ 
/usr/bin/python -E -c pass 
TEST FAILED: /usr/local/lib/python2.7/site-packages/ does NOT support .pth
files 
error: bad install directory or PYTHONPATH 

You are attempting to install a package to a directory that is not 
on PYTHONPATH and which Python does not read ".pth" files from.  The 
installation directory you specified (via --install-dir, --prefix, or 
the distutils default setting) was: 

    /usr/local/lib/python2.7/site-packages/ 

and your PYTHONPATH environment variable currently contains: 

    '' 

Here are some of your options for correcting the problem: 

* You can choose a different installation directory, i.e., one that is 
  on PYTHONPATH or supports .pth files 

* You can add the installation directory to the PYTHONPATH environment 
  variable.  (It must then also be on PYTHONPATH whenever you run 
  Python and want to use the package(s) you are installing.) 

* You can set up the installation directory to support ".pth" files by 
  using one of the approaches described here:

Please make the appropriate changes for your system and try again. 

------------------- 

Has anyone encountered the same problem? I have been trying to correct for
the past few days and I am running out of ideas.
