Another solution, which is more elegant than this way away, is one I
suggested many months ago: Generate real executables that consist of a
stub that dlopens a shared object version of the interpreter, and passes
it the bytecode contained within.  This also gives you versioning of
runtimes and such in a much more elegant way.  The only disadvantage
this has is that you have to have a real linker available.  I don't
think it's all that likely that somebody developing software on their
machine, even if it is in Gambas, won't have one of those.

The traditional way of getting around this is to use #!/usr/bin/env
instead.  (ie, #!/usr/bin/env gbx2, such that the gbx2 executable can be
anywhere, as long as it is pointed to by the PATH environment variable.)
