Someone has released a patched version of mongrel 1.1.5 that will
compile its extensions against 1.9.1 just fine... the link is all over
the comments for mongrel on isitruby19.com, let me look real quick...

This one: gem install mongrel --source http://gems.rubyinstaller.org

Works great for me (just tested it against ruby 1.9.1 on cygwin... it
is a little slow as mongrel on windows tends to be for some reason,
I'll have to try it on my linux box later)
