I posted to Tracker >> Patches on sourceforge as suggested by Georg.
That seems like the best solution since I am new to the project.
FYI, I just realized that i only fixed the portmidi implementation, because that's all really needed.
Yes - most of the work had been done already in portmidi. I basically had to only 1) remove the pd_error messages that sysexin and midiin are supported on linux only and 2) change s_midi_pm so that it could keep track of more than one byte of sysex at a time.
