dmd2-2.052 is only for i386, while you are running amd64 (or dmd2 on FreeBSD)

I run 64 bit Windows 7, where around 70% of my applications are 32
bit, and 64 bit Arch Linux, where multilib lets me install the 32 bit
version of most applications. If you go through the Linux kernel
archives, you'll find that running 32 bit applications on a 64 bit
kernel is actually fairly popular because 64 bit applications need
~20% more memory due to increased pointer sizes.

I don't know whether FreeBSD has multilib support, but it's fairly
common among 64 bit linux distros these days. I wouldn't be surprised
if the Unix folks had it as well.

They probably will, but they're generally one step behind the
reference compiler. Granted, one step isn't much, and they tend to
generate slightly better code than the reference compiler, so it's not
like this approach is wrong.

As has been mentioned, you could also try building DMD as a 64 bit
executable. I think I've done it in the past, but I don't remember
whether I completely finished or not. I don't remember hitting any
large issues though.
