Hi William,
I've reproduced the hang with a ML 10.8.2 (12C53) guest with 1 core and with VMware Tools installed, on my MacPro5,1 host. I simply ran the Gentoo Prefix bootstrap script and it hung in the middle of emerge: (68 of 79) dev-lang/python-3.3.0 Compile. Now I need to figure out what happened...
Cheers,
