[Stk] RtMidi question

[George Tourtellot]

Hello all,

in directory stk-4.1.1/projects/demo
I did:
make Md2Skini
and this worked, but now when I feed in a .mid file, I get the message:
	RtMidi: No OS X MIDI input devices available.

Also, I get a similar message:
	RtAudio: no devices found for given parameters.
when I enter ./Drums.bat, for example.

the only thing I know I haven't done is install tcl and tk, but so 
what?--what am I missing/doing wrong?

thanks,
George
