Yeah I got this far with guile 2.0 as well.

I understand, I know just enough about autoconf to know that }:)
But if I write something that depends on guile, would I have to change
anything in my scripts to use guile 2.0 if I've installed the file as,
for example, guile2.m4?

There's nothing really wrong, I just think it's a little
unnecessary. Since guile seems to be able to live next to other versions
of itself for about 90%. All the library files and script files are
already in a special directory, only some of the other files
(info,m4,guile-tools) seem to conflict.
Anyway, it's not really a problem, it's pretty much just lazyness and
curiosity. I would like to use software for both versions with minimal
patching and I would like to be able to write software for guile 2
without using all kinds of configuration specific to my case.
I should probably just try it with a renamed guile.m4, I was actually
hoping for some recommendations or warnings or stories about how other
people handle it, I don't want to do something that goes completely
against all recommendations.
Thanks for your answer!
