i applied the patch with:

 cat ../jackmix-virtual-fix.diff | patch -p1

than running:

scons configure extraincludes=/usr/local/include/:/usr/include/ 
libdir=/usr/local/lib/:/usr/lib

but running scons i still get this error:

nowhiskey at murija2:~/software/nove/jackmix/jackmix-0.3$ scons
scons: Reading SConscript files ...
Checking for jack...(cached) yes
scons: done reading SConscript files.

scons: *** [jackmix/jackmix] Error 1
scons: building terminated because of errors.
..........

as additional information, two days ago by a fault i deleted the 
/usr/share/aclocal dir with all the scriptes inside of it!!

could it be that this is now missing on my system?

cheers,
