Wow, really? Is there anything in your setup that makes it so, or do you think that's true across the board?

My Makefile has the lines as quoted.



Hmm, looking closer at the Makefile, I don't have a 'gmp/include' or 'gmp/lib' folder, is that the issue? Should it point to /usr/local/ or something?

Any particular motherboard/case recommendations?

I just factored a C148 with SNFS in 26 hours (vs. ~120 with GNFS).
