I did the standard install, moved in some source, compiled it and tried to run it.  The library is there.  On the working systems ktrace shows:

sermons# ll -d /usr/local/lib

I think I found the cause of the problem.  A reboot corrected the issue.  Apparently when ldconfig was run /usr/local/lib didn't exist.  Apparently it doesn't check for that except for in ldconfig.  I was not aware of ldconfig before.  That explains why the reboot worked.  Thanks to all who provided information.
