tesseract @3.00_2+eng Not using leptonica

[jack@…]

TL;DR version: tesseract isn't building with leptonica. Long version:

If install tesseract using:

$ sudo port selfupdate
$ sudo port install tesseract

... I get an install in /opt/local that gives me this on invocation:

Tesseract Open Source OCR Engine with LibTiff

... and fails to handle any PNG I pass it, telling me something like this:

name_to_image_type:Error:Unrecognized image type:fe-1.png
IMAGE::read_header:Error:Can't read this image type:fe-1.png
Read of file fe-1.png failed.

When I look in the configure script, I see that the leptonica check looks like:

 16433  # Check location of leptonica/liblept headers.
 16434  have_lept=no
 16435  for incd in /usr/local/include /usr/include
 16436  do
 16437    for lept in . leptonica liblept
 16438    do
 16439      if test -r "$incd/$lept/allheaders.h" ; then
 16440        CPPFLAGS="$CPPFLAGS -I$incd/$lept"
 16441        have_lept=yes
 16442      fi
 16443    done
 16444  done

... and adding /opt/local/include to line 16435, then re-building, gets me a binary that gives me this on invocation:

Tesseract Open Source OCR Engine with Leptonica

... which happily processes whatever PNG I pass it.
