Hey guix,

Pretty recently, it seems something weird is happening when playing with
guix on the REPL.

On master, 5a947e118fb72b8fb1fd0c8d0b783fc7cde0c461:

--8<---------------cut here---------------start------------->8---
$ guix repl
> (use-modules (gnu packages gnupg))
While compiling expression:
error: guile-email: unbound variable.
--8<---------------cut here---------------end--------------->8---

Loading up the `(gnu packages mail)' module first seems to work around
the compilation error. My best guess is that this has something to do
with a circular reference between guile modules, but I am not certain on
how to easily debug (and fix) this.

Ah!  Glad someone else is seeing this too.  Below's the full 
backtrace if it's of interest to anyone.

I updated the guile-email package two days ago. I hope that is not what
introduced this problem, and I don't see how it could have. Even `guix
build guile-email` on the terminal fails with a guile-email unbound
variable error.

I do not think it was that commit, as I found the offending commit:
c7b2b539802eaa3f969e212c98eb671a1a75e9f3

This is the commit that adds mumimu to gnu/packages/mail.scm, as well as
to the inputs of mumi. Reverting this commit (at least) solves the issue
I had in the first mail.

Could it be that the reference to guile-email in the version field of
mumimu created this issue?

I also spotted this. It looks to me sort of like a copy/paste error, I'm
not sure why this variant of mu would take the version of the
guile-email package.

Anyway, to work around this issue I've pushed [1], which just replaces
the reference with the current value.

My bad!  I copied the definition of ‘mumimu’ from Mumi itself and didn’t
pay enough attention.

The version number makes little sense anyway.  You did the right thing,
thank you, and apologies for the breakage!

This is a copy/paste error.  The origin of this expression is the
guix.scm file of mumi.  Ludo then wrote a mumi service and copied the
definition of mumimu from that guix.scm file.

(package-version guile-email) is obviously wrong.  It should have been
(package-version mu), because mumimu is a fork of mu.

I’m closing this now as mumi no longer depends on a fork of mu; instead
it uses guile-xapian with its own database.
