[erlang-questions] Erlang on ARM9?

[Guy Wiener]

Thanks a lot, Gustav and Matthias, now I see the error of my ways :)
After changing the built option to default, the configuration proceeds, but
get stuck on some missing redundant library.
How do I configure the cross-compilation to build only the bare minimum?  I
don't need auxiliary libs, just basic Erlang.

Thanks again,
  Guy.
