The DMD zips contain all the source code. You should be able to do this:

- Unzip dmd.2.053.zip (or whatever other version you want)
- Go into the 'src/dmd' directory
- Compile dmd (For me, it's just "make -f linux.mak", but I'm on a 32/32 
system. I don't know if you'd need another switch for 64-bit...But you say 
you've already compiled dmd from git, so you probably already know :) )
- Copy the resulting executable to the bin directory: cp ./dmd 
../../linu/bin(32|64)/

That should be all you need. I don't *think* you'd need to to recompile 
druntime or phobos (but then, I'm not an expert on DMD's internals). If you 
do end up needing to recompile them, they're right there in th zip, too, 
'src/druntime' and 'src/phobos'. If you do, the just remember to copy the 
resulting libs from the src directory to 'linux/lib(32|64)/'.

We do really need a better way to compile DMD/DRuntime/Phobos, though. I've 
been meaning to make unix and windows scripts for it, but haven't gotten to 
it yet.
