I'm having trouble getting guile's gds installed and running. I keep
getting

error in process filter: Wrong type argument: listp, Backtrace: [2 times]

Docs say I should have the three gds...el files in guile's "load path". But
apparently I don't know how to do this properly. Or maybe I've got outdated
gds files?

BTW, if gds is not the way to go, can anyone suggest a different way to
debug guile inside of geiser/emacs?

Thanks,
LB
