[SciPy-user] Re: SciPy-user digest, Vol 1 #201 - 7 msgs

Frank,

I had problems building from tar files but after I checked out CVS tree 
directly (as Travis suggested) everything worked fine (including Chaco 
that I installed write after finishing scipy). I am running on RedHat 
7.3 though, so versions for python, gcc, etc. are a bit different.
You can clean your current built by:
python setup.py clean
I don't know why your build wasn't successful though, so maybe someone 
else can help with that...

Good Luck,
-Viktor
