On fedora core 6, when using ruby installed via. yum (i.e. the rpm from the fedora updates repository), the ruby binary is at /usr/bin/ruby, whilst the bulk of the ruby files are in /usr/bin/ruby/
During setup of a new Ruby SDK for a rails module in IDEA, the user is prompted for the location of the Ruby SDK. Due to the method used to verify the correctness of the user choice, this is not intuitive. '/usr' is correct in so far as adding '/bin/ruby' locates the interpreter. However, '/usr/bin/ruby/' does not work, as the interpreter binary is not under this path.
The interface should make clearer the intent here, so that the user can select the correct location without resorting to reading the source code for the plugin.
Environment: fedora core 6 x86_64, sun jdk 1.5.0, IDEA 6.0.4, ruby plugin 3365, ruby 1.8.5, rails 1.2.1
