Here on Gentoo GNU/Linux it's in the xdg-utils package.

Ah, ok.  I wasn't too sure what `dired-current-directory' returns.

Assuming you have xdg-open installed, something like this might do the
trick.

--8<---------------cut here---------------start------------->8---
(defun dired-open-externally ()
  "Open the current directory in your OS's file manager."
  (interactive)
  (start-process "dired-external" nil "xdg-open" (dired-get-file-for-visit)))
--8<---------------cut here---------------end--------------->8---

Then the logic what application to use for opening the given file or
directory is inside xdg-open.  On GNU/Linux it takes these informations
from /etc/mailcap and ~/.mailcap, AFAICT.
