Help with elkhound port development

[Mark Brethen]

This is a build dependency for a program I want to use (and also port). The author does provide a pre-built elkhound for mac os as a separate download. Below is the current state of my Portfile (if you want to check out the source):

description         a GLR Parser Generator

long_description    \
    Elkhound is a parser generator, similar to Bison. The parsers it generates \
    use the Generalized LR (GLR) parsing algorithm. GLR works with any context-\
    free grammar, whereas LR parsers (such as Bison) require grammar \
    to be LALR.
