The configure script is trying to use pkg-config to get the jack-related
libraries and compiler flags.  Please send me whatever you had to add
by hand, and I'll fixup the configure process in the case where pkg-config
doesn't exist.  (Actually, please send all the changes you made -- we
want the build process to work in as many contexts as possible).
