Thank you, Nigko, for persevering. It would be good if Guix’ claimed features had no need for a GUILE_LOAD_PATH clearing work-around. I had not thought anymore that the source checkout can be referenced.
Could you send a patch about the `guix build' diff you debugged to guix-patc...@gnu.org? Preferrably you would drop the whole absolute-dirname’s `if' and canonicalize unconditionally, I guess. Make explicit in the docstring or in comments that symlinks are the reason. `guix build -S' was just an example and a thought. A fix would be nice, especially now that you found the reason, but is nowhere near as important. Regards, Florian
