1. I never bother installing the zip anywhere. If you just unzip it and add 
/path/to/unzipped/dmd2/linux/bin to your path, then you should be fine. I don't 
see any real reason to actual try and install dmd into your system folders 
(though you obviously can if you want to).

2. Assuming that you _do_ move files around, you need to adjust your dmd.conf so 
that it points to the appropriate places.

3. If you just moved files around, then you might not _have_ a dmd.conf, and 
you're doubly screwed.

Take a look at the documentation page for dmd on linux:
http://www.digitalmars.com/d/2.0/dmd-linux.html

It's slightly out of date, since with the last release, 64-bit support was 
added, and the 32-bit version of libphobos.a is in 
/path/to/unzipped/dmd2/linux/lib32 and the 64-bit version is in 
/path/to/unzipped/dmd2/linux/lib64, but the instructions should be correct 
otherwise.

You need to make sure that dmd is on your path and that a version of dmd.conf 
which points to the place where libphobos2.a is is in one of the places that dmd 
looks for dmd.conf (as described on that page). Also, make sure that you're 
using a dmd.conf based on the most recent version, or you could be missing 
necessary linker flags.
