Hey,

I tried out the example in the Cuirass README [1], but I don't think it
worked.

1: http://git.savannah.nongnu.org/cgit/guix/guix-cuirass.git/tree/README#n46

I see the following in the standard output:


2018-11-01T20:55:43 evaluating spec 'guix-master'
Backtrace:

ERROR: In procedure %resolve-variable:

2018-11-01T20:55:44 failed to evaluate spec 'guix-master'


I assume something has actually gone wrong, but I have no idea where
this error is coming from, I can't even find primitive-load-path called
from anywhere in cuirass or guix. Any ideas?

Thanks,

Chris
