[erlang-patches] Erlang on AIX 5.3

[Raimo Niskanen]

For questions about using and building Erlang/OTP, use the 
erlang-questions@REDACTED mailing list. If you have a patch
use erlang-patches@REDACTED If you want to report a bug
use erlang-bugs@REDACTED 

All this can be found at http://www.erlang.org/mailman/listinfo if you
follow the links down to the individual mailing list descriptions. And
that page itself can be found from:
    http://www.erlang.org
    -> FAQs + mailing lists
    -> The erlang.org mailing lists

Since you seem more likely to have a platform specific build problem
than a bug I would go for erlang-questions@REDACTED
