This version of POSIX::RT::MQ has not beed tested on 'hpux' platform.
If you are lucky enough to get it working please drop me a note.
If not (and you know POSIX message queues are supported on this platform)
please inform me anyway - maybe we'll be able to do a port.

Checking if your kit is complete...
Looks good
