Spell checking

[Anders Host-Madsen]

I badly need spell checking for my typing. LyX relies on aspell, 
which I don't have. I went to the aspell web page and 
downloaded, but I find no installation
instructions. I'm lost. I use LyX on a Mac, and it seems aspell 
is some kind of unix thing. 
I can see that cocoAspell is a Mac 
version of aspell. If I install that,
will it also work from LyX? Thanks.
