[Mono-osx] MacDev package not found?

[Jason Perkins]

Trying to get myself set up with MonoMac, following the instructions
from http://www.mono-project.com/MonoMac.

I added the repository http://addins.monodevelop.com/Alpha/Mac/2.4,
then tried to install the MonoMac development add-in. I get the
message "The selected add-ins can't be installed because there are
dependency conflicts. The package 'MacDev v2.4' could not be found in
any repository"

Ideas? I'll go grab the sources in the meantime, but was curious what
the current "official" build looked like.

Thanks!
