Various errors installing gem documentation

[Phrogz]

It's usually some method called on a very large negative Fixnum. Note
below how different install runs produce different errors. (Who said
that computers were deterministic?)

RDoc failure in lib/facets/more/cookie.rb at or around line 336 column

Before reporting this, could you check that the file
you're documenting compiles cleanly--RDoc is not a
full Ruby parser, and gets confused easily if fed
invalid programs.

The internal error was:
