Follow these steps to install Tesseract using Macports:
1. Install Tesseract dependencies: autoconf, automake, libtool, libpng (with support for jpeg and tiff) and leptonica.
2. Install tesseract. (I installed with just the english language support).
3. Set the TESSDATA_PREFIX env variable to point to the location of parent directory that contains the "tessdata" folder, which contains the eng.traineddata file (you may need to do a "find" to locate this file and point it to the correct path).

Usage:tesseract imagename outputbase [-l lang] [-psm pagesegmode] [configfile...]
pagesegmode values are:
0 = Orientation and script detection (OSD) only.
1 = Automatic page segmentation with OSD.
2 = Automatic page segmentation, but no OSD, or OCR
3 = Fully automatic page segmentation, but no OSD. (Default)
4 = Assume a single column of text of variable sizes.
5 = Assume a single uniform block of vertically aligned text.
6 = Assume a single uniform block of text.
7 = Treat the image as a single text line.
8 = Treat the image as a single word.
9 = Treat the image as a single word in a circle.
10 = Treat the image as a single character.
-l lang and/or -psm pagesegmode must occur before anyconfigfile.
Single options:
-v --version: version info
--list-langs: list available languages for tesseract engine
