Ardour config problem with scons : something about coremidi,audiounit .../...

Hi.
On Ubuntu Edgy, I try to configure and compile Ardour but I have that pb :

Checking for C header file /System/Library/Frameworks/CoreMIDI.framework/Headers/CoreMIDI.h… (cached) no
Checking for C header file /System/Library/Frameworks/AudioUnit.framework/Headers/AudioUnit.h… (cached) no
Checking for C header file /System/Library/Frameworks/AudioToolbox.framework/Headers/ExtendedAudioFile.h… (cached) no

I have been searching what package to install (or to compil) but I just can’t figure what to looking for.

Any help would be appreciate.
