there is a symlink handling problem in the pcp suite from SGI. The

package, though).

It would have been nice if you had informed SGI about this problem
before mailing to bugtraq.

As a temporary workaround, remove setuid from pmpost.  Any PCP events
from pmie running as a user will not be logged, this is unlikely to be
a problem.  A full patch will be available tomorrow, after it has been
reviewed.
