.bundle is also used by Git. If you have a Git bundle, use Git to checkout from the bundle. It is basically just a remote repository residing on your filesystem.
Depends on your skill level, you can either download the bundles, then drag and drop them into your Users>my.name>Libary>Application Support>TextMate>Bundles folder, or you can use subversion in terminal like so
mkdir -p /Library/Application\ Support/TextMate/Bundles
cd /Library/Application\ Support/TextMate/Bundles
svn co http://svn.textmate.org/trunk/Bundles/Haskell.tmbundle
