The above message contained the following:

Good catch!

BSD-derived operating systems (FreeBSD, netBSD, BSDi) like Linux
have a non-standard ps(1) utility. I've enclosed a patch to the
ldmadmin.in proto-script that should fix the problem. After patching
your ldmadmin.in in your "src/scripts" directory, you'll have to
reinstall it and reapply any customizations to it (advice: save the old
ldmadmin script for comparison).

Be advised that I'm not a perl expert -- so if it doesn't work, I'd
appreaciate hearing from you.

This change will be in the next release.
