As the message says, your installation has mismatched versions of xparse
and l3kernel. From your log, you have the old 'expl3' packaging for the
LaTeX3 kernel material, rather than the newer 'l3kernel' one. You must
have installed the mismatched files at some stage. Normally, doing an
update should sort this, but with the TL2012 release imminent you may be
better waiting for that.
