[erlang-questions] IPC bus for Erlang?

I tried to add configure test for the mac leopard libs, but I obviously failed.
My configure skills are rather limited.

After you have built and installed wxwidgets.
Add the install dir to the path, i.e. so that wx-config is found in the path

unpack a freash r13a erlang,
run ./configure && make && make install for the complete erlang package.

The separate install script in wx library was intended for standalone wxErlang-releases
before it was included in the erlang distribution. I have some more work to do..
Thanks.
