Yes, install the sse2 instead.

Since you're using debian, perhaps you can read this (Quite old now. I 
don't know if there's any update.)

http://lists.debian.org/debian-devel/2001/11/msg00823.html

which basically says debian can find out which blas to use.

In fact in you configure log, they *are* found.
