Previously this port used library files packaged in the distribution
tarball. However the latest tarball released by Digital Mars contains
library files for only the O/S-architecture supported by the tarball.
The port now builds all libraries and files required to build the port
from source, installing the library needed to run compiled D programs.
The advantage to this is that previously only i386 and amd64 were
supported whereas now this port should install on all architectures.
