Why don't you want to just use LD_LIBRARY_PATH? I suspect, to be

Hi all,
I was looking at the Tesseract wiki, and it states that "The easiest
way to install Tesseract is with MacPorts." I don't think that is
true any more. MacPorts requires XCode to be manually installed
before it can be installed, which doesn't look like it's very simple
for a non-expert.

Hi David,
You're right, that would be useful. Tesseract has a basic version of

However at present they can't be assigned per region, only as

One quick thought, if you're still using .uzn, it's only loaded with
certain psm levels (it is with -psm 6, but not -psm 3, the default).
And it's loaded from .uzn. So if you
have any .uzn files lying around, they will be being applied with
