I recently noticed that the plan9port package is scheduled for removal.

From package.mask:

>  on behalf of QA team
> 
> Missing a dedicated maintainer; problems regarding LDFLAGS
> (bug #335471), overflows (bug #340671), W|X sections,
> and misc problems (bug #224209) as well as missing version
> bumps for about two years now (bug #273890).
> 
> Removal on 2011-03-26

I would like to see this package remain in portage and would therefore
like to volunteer as the new maintainer. I've updated the existing
ebuild using a 2011-03-20 snapshot and have included quite a few
updates, including those from Bug #273890.

I've attached a copy of the new ebuild, additional files can be found
here: http://andy753421.ath.cx/linked/p9p/

It builds cleanly for me on x86 and amd64 machines. I've included fixes
for Bug #273890, Bug #224209, the W|X section issues, and a variety of
other problems. I wasn't able to immediately reproduce Bug #335471 or
Bug #340671 so they may either have been fixed upstream or I will need
more precise steps to reproduce. Some of these fixes are slightly hacky
patch files, so I'm planning on working with upstream for a proper
solution.

However, I am not an official gentoo developer so it sounds like I'll
need a "Proxy Maintainer" to review my work and push updates to portage.
Would anyone be willing to do this?
