Cloned the git sources of dub.
Done:
export CC=gcc
ldc2 ./build.d
Then running build spits out:

Using pre-existing version file. To force a rebuild, provide an 
explicit version (first argument) or remove: 
/home/freebsd/Git_app/dub/./source/dub/version_.d
Building dub using /usr/local/bin/ldc2 (dflags: ["-g", "-O", 
"-w"]), this may take a while...
Command `["/usr/local/bin/ldc2", 
"-of/home/freebsd/Git_app/dub/./bin/dub", 
"-I/home/freebsd/Git_app/dub/./source", "-version=DubUseCurl", 
"-version=DubApplication", "-g", "-O", "-w", " build-files.txt"]` 
failed, output was:
ldc2: for the --version option: does not allow a value! 
'DubUseCurl' specified.
ldc2: for the --version option: does not allow a value! 
'DubApplication' specified.

What is this ?

It gives me the option LDC but it is ldc2 ?

For dmd to specify a version to enable you use ``-version=``, for ldc 
you use ``--d-version=``.

But why is it using ldc2 to compile? Its meant to be using the wrapper 
ldmd2 which swaps the dmd style to ldc2 style.

Also why are you building dub? Does your build of ldc not come with it 
for some reason?

The  native d-compiler on freebsd-arm64 is ldc2. But it comes 
without dub.
[No dmd or gdc is available or they have to be build with 
llvm/gcc/ldc2 ]
