In my opinion it does.  At least unless the problem consists in missing
libraries.  Then it may need mentioning in the dependencies (unless
already listed there), and it may be worth checking that system
packagings of LilyPond also have the requisite dependencies.

But if there is a bona-fide language version problem with midi2ly, of
course it's a bug.  Our prepackaged binaries are a service and
convenience for LilyPond users, but "the" LilyPond is just the source
code.
