Well, that's what I meant as well.

Marius and you have to have the final say about this.

Without having thoroughly thought about it, I'd say it would be
useful to be able to install parallel micro versions, the reason being
that you may trust a certain micro version, but would like to do
development on another.

Maybe that would be a great idea.  I've been trying to keep a
system-level production version of guile-1.4 installed under /usr/lib
in parallel with an experimental guile-1.7.0 under /usr/local/lib.

A real nuisance has been that the libtool-generated link flags contain
both -L /usr/lib and -L /usr/local/lib in a somewhat arbitrary order.
I tried to resolve this, but finally got so frustrated that I simply
moved away all libraries under /usr/lib while compiling guile-1.7.0...

Are you sure, considering what I wrote above?

It seems to me that we'll have trouble as long as we don't include the
version in the library names...
