This is how I do it:

1. Install the latest Debian package (using 'apt-get install
libjack0.100.0-0')
2. Get the JACK source package you need, configure it with
--prefix=/usr, build it and install it (without uninstalling the Debian
package)
3. Remove all files starting with libjack-0.100.0 in /usr/lib
4. Create a symbolic link: /usr/lib/libjack-0.100.0.so.0
-> /usr/lib/libjack.so

Done. Now old JACK programs from Debian packages should work (since the
database thinks that the JACK packages are still installed, although
they really have been overwritten) and programs requiring the newer API
(MIDI etc) should also work. If the libjack ABI ever becomes
incompatible with the old one your Debian packaged JACK clients may
start acting weird though.

Also, your JACK-from-source installation will be overwritten if you do
apt-get upgrade and there are newer JACK packages than the one you have
installed. But all you have to do then is to reinstall your source
build.

There are probably cleaner ways to do this (like copying over the debian
subdirectory from a Debian source package to your new tarball and build
a proper Debian package), but this works reasonably well for me.
