Hi, could you explain me how this error is related to mac_chkexec?

(after enforcing, I execute xchat and get:)
/libexec/ /usr/X11R6/lib/ mmap of
entire address space failed: Operation not permitted
(I set chkexec.enforce to 0, run xchat and enforce the policy again
and the error disappears)

It didn't tell me which executable it could not run.
