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:

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.

Oh.  Hmm, in that case, "service ldconfig restart" probably would have
fixed it.  (Seems sorta strange to "restart" a "service" that just
builds a table and exits.)
