Indeed. This doesn't remove the 'creates the symlinks automatically'
step, but it's still an easier way of avoiding the ldconfig step.

That would probably be a good idea IMO. The question, obviously, is
where - the first place to spring to mind is the INSTALL file, but many
people (especially those who have compiled the program before) are
unlikely to stop to read that; would somewhere in 'configure --help' be
supportable, as the most likely to be noticed, or is that too intrusive?
