Hi,

Sorry for replying so late.  New OSX releses have the
clock_gettime() function while midish is assumuming it's not
available; in turn it defines its own function, which causes
conflicts.

I couldn't find a recent OS X to test, but I think the fix that
just went in should work on your system.  Let me know if this is OK
(the fix is in the new 1.2.1 release or the snapshot).
