The indentation shows that is is a hard dependency of cryptsetup, which is backed up by reading the ebuild. I expect that it needs the device-maper functionality provided by lvm, in which case you can set the device-mapper-only USE flag to avoid installing the full lvm suite. -- Neil Bothwick The trouble with life is that you are halfway through it before you realize it's a "do it yourself" thing.
