SUMMARY: execute permissions on /usr and /usr/local removed

Thanks to Justin, Jeff, Rick and ullyatg who replied.

All our users run on ksh  so the tracking is not a problem - I am fairly
certain this is down to an install by a collegue (gabrielle) which was
done co-incidentally about 10 minutes before people started shouting.
The bit confusing me was the part about the perl which sounded pretty
suspicious.
Thanks a lot guys.
