LMS on pCP nightly updates failing

For all of this week the nightly update 7.9.2 - 53860 is available but when I try the 'nightly update' in pCP first message is

LMS Update Found:
http://downloads.slimdevices.com/nig...860-noCPAN.tgz
Download and update LMS

When I use 'update' the message below appears

/usr/local/bin/lms-update.sh: line 36: /usr/bin/getopt: not found

Any thoughts?

Cheers, David
