GDBM on Ruby 1.6.6 for Windows

I confess to being a frequent Windows
user and a fan of the one-click installer.

But since I installed 1.6.6, I don’t seem
to have GDBM any more.

Can someone tell me how to build it or
send me a binary or something?

I do see a gdbm.h somewhere (I forget
where), but no .c, so I haven’t a clue
about building it. (I do have an old
djgpp on my box, but I really never use
it any more).

Thanks for any help…
