4.5 is an old version.

Homebrew works for me, as does direct download from github.

[elmimmo]

4.5 is the latest version that Homebrew tries to install (see http://braumeister.org/formula/multimarkdown). What version does it install for you and how do you accomplish it?

[elmimmo]

Well, go figure. Homebrew installs 4.5 fine after running:

rm -rf $(brew --cache multimarkdown)

and then attempting again:

brew install multimarkdown
