Trouble installing plugin?

Hello all –

I’m having trouble installing a plugin - exception_notification,
specifically. I’m developing on WinXP / Cygwin, with Rails 1.0 at the
moment.

$ ruby script/plugin discover
$ ruby script/plugin install exception_notification
svn: PROPFIND request failed on ‘/rails/plugins’
svn: PROPFIND of ‘/rails/plugins’: 403 Forbidden
(http://svn.protocool.com)
svn: PROPFIND request failed on ‘/public/plugins’
svn: PROPFIND of ‘/public/plugins’: Could not resolve hostname
`svn.substance-it.co.uk’: The requested name is valid and was found in
the
database, but it does not have the correct associated data being
resolved
for. (http://svn.substance-it.co.uk)
Plugin not found: exception_notification

The plugin process seems mysterious; I’m left to assume that it fires
SVN
requests? I’m not even sure where to begin troubleshooting this…
