If I read it right, we have the following Depends: tesseract-ocr → libtesseract3 → libleptonica (>= 1.69~) So the versioning against libleptonica is already there, and we wouldn't gain anything in rebuilding src:tesseract after that.

I think we can live with that for wheezy. Proper library versioning can happen after that, which is going to need a fix for tesseract-ocr at that time (killing the hardcoded Depends: on libleptonica). [If you still have time to kill, please point involved maintainers to the relevant bits of the Debian Policy for the next release cycle.] Mraw, KiBi.
