Tesseract doesn't have any languages installed

Download some default languages:

• https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.eng.tar.gz
• https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.fra.tar.gz

Because we have defined the TESSDATA directory as /usr/local/share/tessdata, I found the easiest is to download the files (caching them), copy them to that directory and do.
tar -xf tesseract-ocr-3.02.eng.tar.gz --strip-components 2
That will strip the 2 sub-directory hierarchy in the tar and dump the contents right in tessdata

While you are in there, can you modify these lines from

if [ ! -d "$TESSDATA_HOME" ]; then
  mkdir $TESSDATA_HOME
fi

to

if [ ! -d "$TESSDATA_HOME" ]; then
  mkdir $TESSDATA_HOME
  chmod 755 $TESSDATA_HOME
fi

On mine it has 744 for some reason.
