I've given it a try, my jack_load here wants at least 2 parameters, an arbitrary
client name and shared object.

jack_load [ -i initstring ] [ -s servername ] [-w ] client-name so-name [
initstring ]

Giving it the absolute path to shared object (without .so) seems to work. This
is from within the build directory...

    jack_load osc2midi $(pwd)/src/libosc2midi_internal

Seems to load fine in jackd 0.125.0 apart from a warning by osc2midi itself

    Error opening map file! /usr/local/share/osc2midi/default.omm
