[Mac OSX] TextWrangler "run" command not working properly

[Fabio]

Hi to all,
I have troubles with TextWrangler "run" command in the "shebang" (#!) 
menu.
I am on MacOSX 10.6.7.
I have the "built-in" Python2.5 which comes installed by "mother Apple".
Then I installed Python2.6, and left 2.5 untouched (I was suggested to 
leave it on the system, since "something might need it").

I ran the "Update Shell Profile.command", and now if I launch "python" 
in the terminal it happily launches the 2.6 version.
Then I installed some libraries (scipy and matplotlib) on this newer 2.6 
version.
They work, and everything is fine.

Then, I started to use TexWrangler, and I wanted to use the "shebang" 
menu, and "run" command.
I have the "#! first line" pointing to the 2.6 version.
It works fine, as long as I don't import the libraries, in which case it 
casts an error saying:

ImportError: No module named scipy

Maybe for some reason it points to the old 2.5 version. 
But I might be wrong and the problem is another...

I copy here the first lines in the terminal window if i give the "run in 
terminal" command

where the source (test.py) contains just:

#!/usr/bin/python2.6

import scipy as sp

print "hello world"


Any clue?

Thanks
