[natesire]

it is a namespace collision. Need to do something like this...

import Text.Parsec.Indent as P

line 417:
case (P.runIndentParser id topLevelsParser1 s) of

[dmix]

The solution is actually to change:

417 to:

case (Main.runIndentParser id topLevelsParser1 s) of

[mmx900]

I made a dockerfile in my fork to use herbalizer without using Cabal directly, applying the solution.
If you are familiar with Docker, You can use it like docker run --rm -i herbalizer < test.haml.
