I've notice this same problem recently while looking at the build-log of
our GnuCash package.. It seems to be the problem is caused by the Guile
wanting to auto-compile the guild script, and not being able to as it
wants to store the compiled version somewhere under $HOME.

Could a generally applicable solution be to distribute a pre-compiled
guild.go in the store, so that it would use that and never attempt to
'auto-compile' it?  This would effectively fix this problem for good
without having to create workaround such as using environment variables
or setting HOME to a temp dir.

WDYT?
