Has anyone had this before, and know what might be causing the problem?

Thanks.

The error is in the log:

gems.rb:779:in `report_activate_error': Could not find RubyGem oauth (>= 0.3.5)

You're probably using rails 2.3, and need to add oauth to your .gems file.

The problem solved!

Because Rails 2.3.5 and older are incompatible with Rack 1.1.0 my application failed to start. The twitter gem dependencies conflicted with rack so i specified the --ignore-dependencies flag on .gems to ignore Rack and added the other dependencies to .gems manual.

they are:

oauth --version 0.3.5
mash --version 0.0.3 --ignore-dependencies
hoe --version 1.5.1
httparty --version 0.4.3

EVERYTHING WORKS FINE!

Thanks!
