[SciPy-user] Compiling extensions in a virtual environment[fixed]

[Dharhas Pothina]

I've had a similar problem before (don't remember the details now) where virtualenv wasn't importing something correctly. i.e there was an 'import blah' statement somewhere but then 'blah' wasn't available for the rest of the install script. I never did get further in working out what was wrong. I just ended up upgrading my regular install.

OK,
virtualenv magic must have hexed me somehow. After updating to the  
latest SVN in *and* outside of my virtual environment, the problem  
seems to be fixed.
If any regular user of virtualenv could enlighten us and tell us what  
files block the other, that'd be great.
Thx again.
P.
