This is the method signature as of the latest AAF rdoc:

acts_as_ferret(options={}, ferret_options={})

It expects two hashes, defaulting to empty hashes if no arguments are  
supplied. In Ruby you can omit the parentheses for a method call and  
the curly braces for a hash argument if it is the last argument.

A method with the signature

my_method(options = {})

may be used in the following ways:

my_method
my_method({:key => "value"})
my_method(:key => "value")
my_method {:key => "value"}
my_method :key => "value"

So the following call is supposed to work

acts_as_ferret {:fields => ["id", "name", "body"]}, {:analyzer =>  
MyFunkyStemAnalyzer}

You could try parentheses

acts_as_ferret({:fields => ["id", "name", "body"]}, {:analyzer =>  
MyFunkyStemAnalyzer})

which should work in any case since it is the most explicit form.

If you still get a parse error, you might want to post your actual  
code and the error message you get.
