Parallel installation of guile-2.1.x

[Jan Synáček]

Hello,

I'd like to package guile-2.1.x so it could be used along with 2.0.13.
Using --program-suffix during the configure phase is almost what I
would like, but not quite. The problem is that there still are files
(guile.m4 and guile.info + its parts) that would conflict with the
current installation. Is there a good way to achieve this without
moving files around and running sed on them?

Cheers,
