I have this:
$ python
Python 2.6.6 (r266:84292, Sep 15 2010, 16:22:56)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.getenv('LINES')
>>>
$ python -S
Python 2.6.6 (r266:84292, Sep 15 2010, 16:22:56)
[GCC 4.4.5] on linux2
>>> import os
>>> os.getenv('LINES')
'35'
>>>
I hope it helps narrow things down somewhat.
