I tried to reproduce Pavel's results this afternoon and failed.  I
read the documentation:

http://developer.postgresql.org/pgdocs/postgres/textsearch-dictionaries.html#TEXTSEARCH-ISPELL-DICTIONARY

...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?
