[web2py] Strange import problem: is sys.path not used in web2py?

[Daniel Gonzalez]

Hi,

I have a problem with an import in my model:

Traceback (most recent call last):
  File "/installdir/web2py/gluon/restricted.py", line 212, in restricted
    exec ccode in environment
  File "/installdir/web2py/applications/wavilon_portal/models/db.py", line 
10, in <module>
    import nltk.data
  File "/installdir/web2py/gluon/custom_import.py", line 77, incustom_importer
    raise ImportError, 'Cannot import module %s' % str(e)
ImportError: Cannot import module 'nltk'

I thought this would be a problem with sys.path, so I am displaying it in 
the top of the controller (<sys_path_in_model>)
Then I am doing, manually in the python interpreter:

import sys
sys.path=<sys_path_in_model>
import nltk.data

But this is giving no error!

What is happening here? Is the import mechanism in web2py using something 
different than sys,path?

Thanks,
Daniel
