If you apply that patch and export GAMBAS_ROOT=.../gambas342/, your gbx3
will not use /usr but .../gambas342 instead to search for its stuff (most of
its stuff). I think this is what you wanted, no?

As I said, I don't think that you can create a well-behaving portable Gambas
distribution as there are some hardcoded uses of the /usr prefix in the
source code of at least the IDE. These portions will likely fail when you
execute your portable Gambas in an environment where no normal Gambas is
installed.
