[Samba] Unable to configure 2.2.4 on HPUX 10.20 (locking not available)

[Ed Rodgers]

While running configure on samba2.2.4 source on an HP-UX 10.20 OS, I get the
following:

checking configure summary... ERROR: No locking available. Running Samba would
be unsafe
configure: error: summary failure. Aborting config

What exactly does "No locking available" mean, and is there a workaround?  I'm
currently running version 1.9.15p8 on the same OS.

TIA!
