ok, that should be fine then

yup, but we should be able to deal with it...

fwiw /usr/local/ should be safe for installing, as /usr/ *should* be where
distro installations go to (this is the case in umbuntu) - meaning you can
safely install things there without breaking distros, I'm no expert on
this though, so this might not be the case with them all.

ok, I'll change this

I remember this from somewhere. For some reason I think it has to do with
having to crc all the files where it installs to so it can check if things
have changed. It might be worth upgrading scons, but I'd see if it
magically disappears first.

change COLLECTS_LOCATION at the top of main.cpp
I think I'll put this in the fluxus startup file to make it easier to change.

yep, none of the docs have been updated yet.
thanks for taking this on, see if you can get it to run, in the meantime
I'll make some changes to make simple to modify these things.

cheers,
