On one hand, I agree that the import of '(guix ui)' here feels "hum, it
seems an incorrect location", but...

...on the other hand, where 'build-program' is called, i.e, 'build,
there is:

--8<---------------cut here---------------start------------->8---
        (format (current-error-port) "Computing Guix derivation for '~a'...  "
                system)
--8<---------------cut here---------------end--------------->8---

which is UI, no?  Idem for the message "You found a bug".


Well, I am unsure about the addition of '(guix ui)' and by
'with-error-handlng' in 'build-program'.  However, maybe the exception
handling could happen in the 'build' part.  WDYT?


Cheers,
simon
