Well I was checking how to compile with autotools to binaries with just one
make call but I didn't find any way to do it. Of course I need to find a
solution to get an acceptable upstream release.

I ran now, and cgminer works like you've shown above for about

Yes after a couple of minutes ruining with I got this segfault. I
will check it carefully.
