Well, I've posted questions specifically about ubuntu 64 and got responses
back from them.  The only way that any of us (that participated in the
discussions) got it to work on ubuntu 64 was with a 32 bit chroot.  If you
can figure out the complete list of packages to makes dmd work under ubuntu
64, please tell me!  Ubuntu 64, by default, runs only 64-bit applications.
