Can DMD D2/Linux do this yet?
dmd can't do it yet. But if all you want is to link a against a shared
library you can try the following:
1. Create a shared library
$ gcc -m64 -fPIC -shared shared.c -o libshared.so
2. Building (without linking using dmd)
$ dmd -m64 -c dynamic.d -ofdynamic.o
3. Use gcc as linker
$ gcc -m64 dynamic.o /path/to//libphobos2.a -L. -lshared -lrt -o dynamic
4. Execute
$ ./dynamic
Hello from shared
I attached the files shared.c and dynamic.d, if you want to try
yourself.

Jens,
Two questions - first, what steps do we need to take to convince the
linker call from within dmd to work as above?
Never thought about that. Just tried.
$ dmd -m64 dynamic.o /path/to/libphobos2.a -L-L. -L-lshared -L-lrt -ofdynamic
works.
Great. Wonder why the path to Phobos is still needed - does using -L
preclude all implicit uses of it?
Second, how about the converse - loading a shared library from a
program written in either C or D?
Don't know exactly what you mean. As far as I know dmd is not able to
generate shared libraries. Is that your question?
Yah, I was wondering if it's just PIC generation or something extra.
