did you try to the gentoo forums? there are quite a few planeshift threads there ...i got my ebuilds to work
AFAIR the trick was to use this instead of a normal emerge after you emerge CS and CEL:
CRYSTAL=/opt/crystal CEL=/opt/cel emerge planeshift
and then run PS as:
CRYSTAL=/opt/crystal CEL=/opt/crystal planeshift
try it, and visit the forums ...you\'ll get it to run soon :]
