Homebrew install doesn't work

Homebrew won't download and install because of cert issues during the install process. This is specific to this recipe, it fails trying to get sbt0.12.1, but I can install SBT directly.

Which Homebrew formula are you referring to? I install scala (2.10.3) and sbt (0.13.0) via homebrew, and conscript (0.4.4) is installed successfully for me using the command curl https://raw.github.com/n8han/conscript/master/setup.sh | sh

Is/was conscript part of the Homebrew?
