You've got two options at the moment:

1) Manually grab the version you want and then install the gem file.
I'd do it like this:

	$ wget \
	$ gem install mongrel-

2) Install the pre-release.  This is always just one version.  It's
released fairly frequently but we try to keep it stable.  You can do
this with:

	$ gem install mongrel --source=http://mongrel.rubyforge.org/releases/

If neither of these are good, and other people would like to just
install the current version without a prompt, then I can setup
a /current/ gem source that's like /releases/ but it just contains the
current production release.  But, at least try the other two options
before making me do work. :-)
