As I said before, you could do that for the initial port, say 
cross-compiling a build of ldc master for DragonFly by using ldc 
master on linux.  However, from then on, you'd either be stuck 
requiring all your DragonFly users to do the same or checking 
that cross-compiled DragonFly binary into a binary package 
repository somewhere.  I don't think any OS does this, as usually 
the binary packages are all built from source.

However, most source package repositories like ports expect 
everything to be built from source, so you'd still have to port 
2.067 and any other bootstrap D compiler versions needed to do 
everything from source.

This is the lock-in that keeps most systems tied to C/C++, but we 
have no choice but to adapt to that.  If and when dmd gets into 
the base OS now that it's boost-licensed, as some want to do for 
Fedora and elsewhere, that changes for those platforms.

Except you'd still have to port that gdc to DragonFly first, so 
gdc changes nothing about the above equation.
