Tesseract description should indicate required steps post-install steps

[office@…]

The port description ("port info tesseract") should indicate the necessity of two manual install steps after "port install tesseract":

1. export TESSDATA_PREFIX=/opt/local/share
2. add at least one language file (e.g. eng.traineddata); see comment at bottom of ​this page

I've found these two steps necessary when installing tesseract @3.02.02_0 with MacPorts 2.2.1 on OS X 10.9.

Actually they should be put in a notes block and be accessible by port notes tesseract. Or maybe a page should be created on the HOWTO wiki page about it.

In the future, please Cc the port maintainers (port info --maintainers tesseract).

I'm going to check if we still need this. My feeling is we probably do.
