I think I have it working now. $PACKAGE_DIR seems to work and do what I want it to do. Thanks for the help.

It's not a problem that needs to be solved *in* GDC, but it has to be tackled *for* (packaging) GDC, as you need to have a bootstrap compiler available. Hence, building a C++-based compiler is less complex than a D-based compiler – that is, if you don't want to depend on a pre-existing D compiler, but are fine with using a pre-existing C++ compiler, which is what the LDC snap packages currently does.

I've spoken to the author.  I'm of the opinion that this is a design choice, not something that should be considered an inherent complexity.
