Hmm, I had hoped that with the newest Guile, simply adding the repo's
root directory to the load path would work, at least when invoked with
the --r7rs switch, but it seems that Guile still chokes on library name
parts that are integers.  That's an incompatibility with r7rs that's not
mentioned in the manual.

I guess the only way to make the modules work is to rename all the files
and change the library names to not use integer parts.

Maybe I'll make a guile-compatible standalone package for the SRFI-64
implementation, since that's the most fancy thing in that repo.

I might do it in the following days since I'm on a vacation, but... the
vacation is supposed to be a vacation. :-)  Work has been really burning
me out in the last year.

If someone else feels like trying: all you have to do is rename .sld
files to .scm, change the integer parts of the module names to symbols
(e.g. s64 instead of 64), and rename the directory '64' accordingly.
