This is what I get; my ghc-ios-scripts clone is at b4a8022; I'm on OS X 10.9.5 with GHC 7.8.3 from HT:

I found this line in the installation script:

find . -type f -not -name .DS_Store -not -name "*.a" -print0 | xargs -0 sed -i '' 's|/Users/lukexi/Code/ghc-ios-scripts/||g'

— copy and pasting it into Terminal.app yields:
