The two lines referenced above reference gpgme, and
'guix gc -R $(guix build gpa) | grep gpgme' does show that gpa does
reference gpgme. However, 'guix gc -R $(guix build gpa) | grep gnupg'
doesn't show anything, so it seems that this might be where the problem
is.
'./pre-inst-env guix environment --pure --ad-hoc gnupg gpa -- gpa' does
allow gpa to start without any errors.


While persuing this bug I noticed that gpa looks for gpg2keys_ldap,
which may have been depreciated in favor of dirmngr_ldap. I don't
(knowingly) fetch keys over ldap so I don't know if the fix I made
actually does anything. With it 'guix gc -R ...' does reference gnupg,
but it doesn't on its own cause the program to suddenly work without
having gnupg explicitly installed.

It seems that many distros separate the dirmngr binary which is required
for GPA to work from the gnupg binary, but if that's the case then it
should still find dirmngr with my patch and work for some things


On the other hand 'guix gc -R $(guix build gpgme) | grep gnupg' doesn't
yield any results, so there could be a problem there too.
