Can't subscribe to gradle-dev mailing list

When I send an email to dev-subscribe@gradle.codehaus.org, I eventually get a response (this one took several days):

MAILER-DAEMON@mail.codehaus.org

Hi. This is the qmail-send program at mail.codehaus.org. I’m afraid I wasn’t able to deliver your message to the following addresses. This is a permanent error; I’ve given up. Sorry it didn’t work out.

dev-subscribe@gradle.codehaus.org: /usr/bin/env: ruby: No such file or directory I’m not going to try again; this message has been in the queue too long.

Thanks for the report. I’m taking this up with our service provider.

For reference: http://jira.codehaus.org/browse/HAUS-2286
