I have managed to compile the .a files manually.

I was able to find several “build_dependencies.sh” files for compiling the leptonic a and tesseract.
I had to make several changes to the script so it now work with Xcode 5.

Wrote instructions how compile using the “build_dependencies.sh” script.
The script was unable to build leptonica because a space was missing when invoking “lipo”. Now the entire script can run again.
Merge pull request #14 from neoneye/master
