Here's a guess, I seem to remember another with a similar situation.  The
core2 support is rather new, as in very new.  The current compiler on your
system doesn't support it, although one build from sources should.  If IIRC,
the original thread contained a workaround, but simply setting it to core
for now should be fine, and you can change it once the world is installed.
