MySql adapter error

Most likely due to something I misconfigured and/or broke when trying to
get
the new polymorphic acts_as_taggable to work…In short, after
installing
that gem and then trying to run gem install mysql on my windows server,
I’ve
been getting this weird error on every page I try to hit.

If anyone give give me any insight into how I messed this up or how to
fix,
it would be much appreciated.

The error is

Mysql::Error: #42S22Unknown column ‘joinsincludeconditions’ in ‘where
clause’: SELECT COUNT(*) FROM meal_names WHERE (joinsincludeconditions)

If I take the “rails” folder out of my vendor folder, I don’t get the
error
but just a blank screen. Here’s the rest of the error (well, some of it
anyway):
