These scripts specifically target an older version of ISL. To install it brew install isl011 isl012 cloog018

I am working on a homebrew version of this script.
EDIT: I just noticed that cosmo0920 (https://github.com/cosmo0920/homebrew-mingw_w64) has already begun to work on a brew version of this script.
