Yeah, Tom de Vries as well.

I consider this a bug in guile -- it installs 'guild' with this:
#!/usr/bin/sh
# -*- scheme -*-
exec ${GUILE:-/usr/bin/guile2.2} $GUILE_FLAGS -e '(@@ (guild) main)' -s
"$0" "$@"
!#
Allowing a system script to pick $GUILE here seems weird, especially for
a versioned install of "guild", where as you can see it already knows
the correct guile to use.
However -- I think it's better to just work around this.
I plan to back out this change. Anyone needing to re-run cgen (which
itself ought to come with smarts here, but since it is un-maintained...)
can just specify this by hand. I.e., the status quo ante.
I'll try to send a patch tomorrow.
Tom
