Probably because you don't have gnome installed? Most of the gnome libs
use pkg-config.

The contents of pkg.m4 (ie PKG_CHECK_MODULES) will always be in
aclocal.m4 for a distribution, provided the distribution-maker has
pkg-config installed. Then it's only necessary to find out if the
pkg-config executable exists. This is one way of doing it. If it doesn't
exist, you could also check for jack without using pkg-config. For this
patch, the configure just stops. The error message could be more
friendly.
If jack.pc is not found in any of the specified locations, an error
message will be displayed and the configure will continue with
with_jack="no".
I 'spose you could also have a --with-jack=/opt/some_place_for_jack type
option, if you want to stay away from pkg-config.
