I was trying to get it to run on my G4 powerbook 867 w/ 10.3.9 and with Jack running and X11 and got this console reading:
_=/usr/bin/env
dyld: /Users/paulhammond/Desktop/Ardour.app/Contents/Resources/bin/ardour Undefined symbols:
/Users/paulhammond/Desktop/Ardour.app/Contents/Resources/bin/ardour undefined reference to _jack_recompute_total_latencies expected to be defined in /usr/local/lib/libjack.0.dylib
Any Ideas?
