There are at least three problems with the Guile bindings for mailutils:

1. the Guile source files are not compiled.

2. the Guile source files are installed to $out/share/guile/site/ and
are thus not found with “,use (mailutils mailutils)” in a Guile REPL.

3. the Guile session segfaults when loading the module:

Are the bindings not usable with Guile 2.2?

Thank you!

I was hoping to use some procedures from Mailutils to simplify parsing
Debbugs emails, so that I don’t have to implement, say, a parser for
Quoted Printable string encodings.  I’ll play with this for a while.

I’m closing this bug now, because I guess this will all be fine with the
next release.
