Re: Importing Cheetah.Template.Template unusually slow?

Just downloaded the tarball from http://pypi.python.org/pypi/Cheetah/2.4.2.1 
  and I'm seeing similar compile problems to the ones reported below.

I'm on OS X 10.5.8, using python 2.5.1.  When I unpack the tarball and  
do python setup.py build, it spits out this:

...

...

and then the C version of the namemapper doesn't import because of  
missing symbols.

Is there another build out there that fixes this, or is it still in  
the pipeline?

(And thanks for all your hard work!  Cheetah is great!)
