1) this is a weakness of either SCons' design or our use of it.
-h/--help does indeed do that BUT only after it gets all the way to the
end of our SConstruct file. if it runs into a problem before then then
the --help action is never taken. who's to blame for this? i am not

2) you should know already that having 2 JACK's installed is a recipe
for pain. nasty pain. irritating pain.

3) if you insist, the path ahead is rocky, but also nothing to do with
scons. you need to set PKG_CONFIG_PATH and possibly LD_LIBRARY_PATH to
point include your alternate directories, before running scons, and
before running ardour.

4) you can install newer JACK right over the top of older JACK, and
other than on Debian-derived systems of some vintage, it will just work.
many people do things this way.

its been removed. it was full of old information that was never updated.
documentation is online. thats the only sensible source for it at this
