Hi! Sean, thanks a lot for ghostess! Take a look at the patches if you have time. -execlp patch fixes things on 64-bit architectures: execlp() expects its arglist to end with NULL, not 0. And on 64-bit architectures they are different (0 is 32-bit int, and NULL is 64-bit pointer). -configure and -jackmidi patches are from gentoo proaudio overlay and are included for completeness. Regards, Dmitry.
