guile-hall error on probably every command

[Zelphir Kaltstahl <zelphirkaltstahl@posteo.de>]

Hi Guile users!

I was about to follow the guile-hall tutorial posted on the list today,
but unfortunately, I get an error the first time I need to input a
guile-hall command:

Any ideas, what could be the problem with my guile-hall?
