We'd definitely keep --prefix.  I think many of us use it all the
time, even under a distribution like Debian/RH, etc. for local
compiles.

Sure, I'd expect this to still work fine.

Maybe -- now that we're talking about this again, I have the feeling
that I thought about the -L/usr/lib/guile/VERSION trick a while back
and rejected it for some reason :/  But if it works for guile, others
should also be able to use /usr/lib/FOO/VERSION for their own version
specific .so -> ../../libFOO.so.X.Y.Z  symlinks.

Actually I was thinking of ${bindir}/guile-X.Y{,-snarf,-config,...},
and perhaps an easy way to create the non-versioned symlinks.

this means that in the pkg approach, you'd probably have
/usr/pkg/guile/1.4/bin/guile-1.4, etc., unless we arranged for
--opt-style-install or similar.

right.

This one is somewhat harder if we have any cross-links.  AFAIK there's
still no good solution for this, and if there is one, I'd *love* to
hear about it.  It's a real pain wrt the emacsen...

what I was thanking about is

  lib/guile/1.8/libguile.a
  lib/guile/1.8/libguile.la
  lib/guile/1.8/libguile.so -> ../../libguile.so.15.0.0
  lib/libguile.so.15
  lib/libguile.so.15.0
  lib/libguile.so.15.0.0

of course as I mentioned, we may have to have an enhanced ltdl before
this would work because we'd really need something like

  lib/libguile.la.15.0.0

rather than the above .la file.
