I tried to reproduce Pavel's results this afternoon and failed. I
read the documentation:
...and I followed the link to ispell. And I installed it from
MacPorts. And then I built it by hand, too. And I'm still confused.
Because I don't see anything in either set of results that looks like
the right set of files to use with CREATE TEXT SEARCH DICTIONARY.
What am I doing wrong?
