Package: emacs,mh-e
Version: 26.1
Severity: minor
It's a long-standing issue that simply loading mh-e.el (eg when building
Emacs) often prints "No MH variant found on the system".
Ref eg https://sourceforge.net/p/mh-e/bugs/484/
Here's an attempt at a fix.
I have no systems configured to read mail with MH,
so this is largely untested.

Hi Glenn, thanks for the patch. I ran it through some tests and made a
couple tweaks.
The first tweak is needed for the patch to be usable. Without it, MH-E
recognizes which MH variants are installed, but it doesn't pick one,
which breaks both reading mail and sending it. I fixed that by adding
(or mh-variant-in-use (mh-variant-set mh-variant))
to #'mh-find-path.
The second tweak improves the error reporting in the case where no MH
variants can be found. It's independent of this fix, but the issue came
up in my testing, so I figured I'd deal with it now.
The patch with both tweaks included is
