Installing manually into default locations without un-installing the systems 
package *will* break things. And even then you need a way of telling the 
system to not overwrite your installed package with the systems one again.

So its far easier to install you custom freebob (and possibly jack) in your 
home-dir and have the LD_LIBRARY_PATH set up in your .profile or .bashrc...

Even if the device claims to have this mixer, there is no guaranty that it 
actually does mix something. On the Firepod changing the volumes of 
the "mixer" changes exactly nothing.

Pieters plan is to ditch OSC and introduce DBUS. With that it will be possible 
to write small apps that control the devices mixers. (As the python-apps in 
support/mixer do for some devices already.)
The test-programs should be ditched before the release imho...
