Both mcrypt and libmcrypt are available through the linked website.  You simply have to click the "Browse all files" or similar link once on the "development site" and not just look for the default Sourceforge download button.

there are no instructions included with the sourceforge download.

After php 5.3 mcrypt is automatically included and enabled.
(i was looking to enable an extension)

mcrypt is built in for PHP 5.3.x on windows, you don't need to do anything with a dll anymore.

If installing libmcrypt from RPM, you need both libmcrypt*.rpm and libmcrypt-devel*.rpm. I found RPMs for both were available for most platforms on this page:

http://rpmforge.net/user/packages/libmcrypt/

Also files.edin.dk does not seem to carry the win32 files anymore.
