I see your point, but I=E2=80=99m not entirely convinced.  :-)  After all, =
the
name that appears, be it at the end of =E2=80=98guix build=E2=80=99 or in t=
he profile
created by =E2=80=98guix package=E2=80=99, is =E2=80=9Cgpgme=E2=80=9D, not =
=E2=80=9Cgpgmepp=E2=80=9D.

We could make the messages more verbose, but in general it=E2=80=99s unclear
that it would help.

However, that=E2=80=99s another situation where colored output could help m=
ake
useful messages more visible.

Thanks,
Ludo=E2=80=99.
