With a slight command adjustment, it works for me. You just have to get
the magic incantation right.  And be careful, mispronouncing the spells
can get you turned into a frog or something. :-)

It would be cool if the entire problem with dynamic programs was this
simple.

Here is what I did:

	cc -Wl,--export-dynamic main.c -o main
	cc -c -fPIC fred.c
	ld -x -shared fred.o -o fred.so
	./main

(For testing it doesn't matter, but to install this successfully note that
the script needs a -rpath and a -soname also.)
