newbie seeks repo for markdown

[don fong]

hello, i am looking for advice regarding the best repo from
which to download "markdown" for use on a mac.

on my ubuntu machine i just installed some standard markdown
package with apt-get.  but i have not found anything
equivalent for my mac machine.

i am looking for a maintained package from a reputable repo
site that can be automatically installed and upgraded using
the packaging tools.

i did find the macports package p5-text-markdown, but it
seems not to contain the actual "markdown" filter nor
"Markdown.pl".
