tests failing on homebrew install

[sbma44]

Homebrew has moved up to Tesseract 3.02; the README has specific references to 3.01's directory structure.

• I tried copying the training data files into the apparent directories used by the 3.02 brew install

  cp ./share/eng.traineddata /usr/local/share/tessdata/
  cp ./share/configs/alphanumeric /usr/local/share/tessdata/configs/

  but the tests still fail.

• I tried downgrading to the 3.01 homebrew version of Tesseract, but changes to the latest XCode seem to have broken the way that it assumes autoconf will work.

• Using tesseract directly confirms problems loading relevant image processing libraries. after brew reinstall libtiff and brew reinstall libjpeg, TIFF support is still screwed up. This appears to be a problem with the leptonica recipe. I finally overcame it with brew reinstall --with-libtiff leptonica

This was a complete disaster, and I'm unsure where the fault lies. Clearly not with pdf-extract (other than the README referring to the wrong location for tesseract training date)! But other users will likely come across this, too.

UPDATE:

The README is also lacking a reference to copying around dia.traineddata.
