contributing to macports

[Yury Selivanov]

Hello,

I have a custom ports tree that I've been actively maintaining and using for myself: https://github.com/1st1/ports-overlay

If it's possible, I'd like to contribute some of it to the main line, particularly:

- nginx +lua variant
- postgresql database with 'contrib/hstore' option (this is a very trivial patch to the original port)

- cassandra database
- riak database

- everything else worth interest (lots of python packages for instance)

Please advise me what the next steps might be.

Thank you,
Yury Selivanov
