LDC2 Status

[dsimcha]

I tried LDC2 for Linux out last week and again last night.  I didn't 
spend much time on it on either attempt, but so far I haven't been able 
to get even Hello, World to compile.  It seems like the instructions for 
building druntime, etc. are horribly outdated, the patches bit rotted, 
etc.  Has anyone managed to get past these hurdles and compile Hello, 
World lately?  If so, would you mind posting some instructions?  If LDC2 
is, in fact, mature enough that it would be worthwhile, I'd like to test 
it out, file bug reports, etc.
