… and never mind that I don’t have to do it, I’m a Gentoo kinda guy and I want to do it.
But the Blender source-compile always seems to crap-out in the sound stuff. My system uses Alsa. There doesn’t seem to be any sort of ./configure script in Blender.
I assume you’re using Gentoo on the system you’re trying to compile it on. In such case, Blender 2.40 is in portage. No need to compile it outside of portage, unless you want CVS.
