Hi Simon,

Yes, a pretty good idea:

Apparently, guile.m4 expects that anybody using it ought to have
read and understood all the contained comments:

In other words, using guile.m4 requires using gnulib.

I was "lucky" in that it worked in my environment.  I think the correct
fix is going to be to scrap the guile.m4 file.  Not because I want to
duplicate their code myself, but because autogen still has glitches that
cause gnulib usage to fail, meaning config.rpath is out.  Besides, 50% of
my build time is involved in running configure and configure takes twice
as long using gnulib, so it isn't clear I even want to wholesale import
gnulib.

Anyway, thank you for prodding me on this issue.  I'll try to rip it out
next weekend.
