I installed Ruby via the RubyInstaller 1.9.1 RC2 available from rubyforge, updated gems, and installed rails. Everything worked fine using webrick. For fun, I installed mongrel using "gem install mongrel". The installation went fine:
Successfully installed gem_plugin-0.2.3
Successfully installed cgi_multipart_eof_fix-2.5.0
Successfully installed mongrel-1.1.5-x86-mingw32
3 gems installed

Now, when I start the webserver using "ruby script/server", I get the error:
"The program can't start because msvcrt-ruby18.dll is missing from your computer."
Then, webrick starts and runs normally.
I'm guessing its a issue using Rails 1.9 and mongrel expects 1.8? (I'm new to rails and there is no real reason for me to use mongrel.. just poking around)
