THAT WAS THE CLUE!
(that which follows is how I proceeded to the answer after that clue.)
  dmd -version
Error: unrecognized switch '-version'
and
dmd --version
Error: unrecognized switch '--version'
but
  dmd
DMD64 D Compiler v2.066.1

So thanks, that was the clue that I needed to fix the current problem.  
(Once I have I'll probably be back where I started, but that's not 
certain.  That 2.066..stuff is one of my attempts to investigate what 
exactly was causing the problems, which must not have gotten completely 
uninstalled.

Yeah, now I'm back to:
...
/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libphobos2.a(aaA_4f5_2d5.o): 
relocation R_X86_64_32 against symbol `__dmd_personality_v0' can not be 
used when making a shared object; recompile with -fPIC
...

and
dmd -defaultlib=libphobos2.so test.d
yeielding
/usr/bin/ld: test.o: relocation R_X86_64_32 against symbol 
`__dmd_personality_v0' can not be used when making a shared object; 
recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
--- errorlevel 1

but
dmd -defaultlib=libphobos2.so -fPIC test.d
works.  It shouldn't be required (as in the default /etc/dmd.conf should 
handle it correctly, but I can deal with it now.
