is RtMidi license DFSG-free?
I'm thinking about building a package for RtMidi , as I'm
developing a package of a software that embeds it, and already found
some other packages in the archive doing it. I'm not very keen on
having duplicated code around. In any case, the license , a custom
licensed based on MIT, seems to be a bit wierd:
RtMidi: realtime MIDI i/o C++ classes

Especially this part: "Any person wishing to distribute modifications

developer so that they can be incorporated into the canonical
version.", can it be considered DFSG-free?
There are at least two packages already in the archive embedding this
code, so it's probably already been considered DFSG-compliant, unless
it is an error, but I want to be sure about it.
Greetings and thanks,
