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

And I'm sure that bug reports for dmd that were from a 64 bit build of the compiler itself would get addressed.  So,
while it might not come with a pre-built 64 bit binary, that's not a particularly large stumbling block.
