Trouble getting Alsa to configure

[dotto@uchicago.edu]

Seems the more issues I solve, the more pop up.I have downloaded and unpacked 
the alsa-driver source from alsa-project.org, but when I try to ./config, I 
get an error saying The 
file /lib/modules/2.6.3-ben2/build/include/linux/version.h does not exist, and 
to specify another directory with kernel sources (default is /usr/src/linux). 
I've downloaded and unpacked the kernel-source from 
pramanikconsulting.com/debianppc in my usr/src, and symlinked it 
to /usr/src/linux, but I still get the same error. how do I get this 
configured? 
 
Thanks again, you all have definitely been extremely helpful so far.
