I have just tried it:

1. There is a configuration issue which I hope Brendan will sort out - the x86_64 platform is not correctly detected.
    I ignored this and compiled it anyway.

2. "geng -u -c 10" (about 12M graphs) takes 12s on the AMD 3400+ cpu, about twice as fast as my
     Pentium 4 2GHz machine.
