Hi there,

Lens is OS X only and a little experimental. It also requires special build flags for OS X frameworks. These build flags are not available in luarocks. I proposed a patch which was not included but things might have moved on this subject since then.

If you need a binary version of lens, I made a zip of the version I used for my last show: http://lubyk.org/en/download/document414.zip

Tell me if you stumble on any problems with this binary. I'll get in touch with Hisham (Luarocks) to see if something has changed with this "Framework" feature.
