Can you continue this discussion directly with me at stephen at FreeBSD.org?

I am happy to work with you as hard as I can to resolve this issue, but 
I am mystified.  I created the sage port on the amd64 using 
FreeBSD-Stable-8.2, which is almost identical to what you have.

Somehow python is not finding the libm library, which is where log2 is 
defined.
