Bulding latest DMD and associated projects from github master

[Rob T]

First I cloned everything from github master, and that went well 
but I'm now  encountering a lot of silly stumbling blocks due to 
inadequate documentation, for example it's clear how to build 
anything - period.

There may be documentation somewhere(?), but all I could find was 
this external blog post
http://xtzgzorex.wordpress.com/2011/07/31/d-building-dmd-and-phobos-on-linux/

The instructions in the blog allowed me to successfully build DMD 
src with 64-bit arch on Linux. So far so good, but I'm sure this 
is not the end of the problems I'll encounter.

Being new to this, I'll know immediately where the documentation 
is failing, so as I get stuck and unstuck I'm in a good position 
to create missing documentation or improve on the current 
documentation.

If I'm to try and contribute, I have a few questions, for example 
can anyone contribute at this level (build process)? If I am 
allowed to contribute, then what's the process for making 
contributions?

Thanks.
