tesseract @3.05.01 fails to populate /opt/local/share/tessdata

[rpspringuel (Fr. Samuel Springuel)]

When upgrading to tesseract 3.05.01 the /opt/local/share/tessdata folder is emptied except for the language training files installed by the appropriate language data port. This means that the configs and tessconfigs folders (and their contents) and the file pdf.ttf are missing, thereby hobbling tesseract. These files were present in previous version, though I have cleaned up my MacPorts installation since I last used tesseract, so I'm not sure which version number that was. I was able to find and restore those folders/files in my TimeMachine from March 17th and some personal logs seem to indicate that I upgraded from 3.04.01_0 on that day so whatever version was available on that day most likely had them.

tesseract: build with autoconf

Both autoconf and cmake are supported, but the later does not install the
${PREFIX}/share/tessdata files, without which the program loses many
important capabilities.

Autoconf also appears to be the recommended method according to project
documentation:
