you need to call rails with a project name:

$ rails --help
Usage: /opt/local/bin/rails /path/to/your/app [options]
Options:
-r, --ruby=path Path to the Ruby binary of your
choice (otherwise scripts use env, dispatchers current path).
Default: /opt/local/bin/ruby
-d, --database=name Preconfigure for selected
database (options: mysql/oracle/postgresql/sqlite2/sqlite3/frontbase/
ibm_db).
Default: sqlite3
-f, --freeze Freeze Rails in vendor/rails from
the gems generating the skeleton
Default: false
Rails Info:
-v, --version Show the Rails version number and
quit.
-h, --help Show this help message and quit.
General Options:
-p, --pretend Run but do not make any changes.
–force Overwrite files that already
exist.
-s, --skip Skip files that already exist.
-q, --quiet Suppress normal output.
-t, --backtrace Debugging: show backtrace on
errors.
-c, --svn Modify files with subversion.
(Note: svn must be in path)
-g, --git Modify files with git. (Note: git
must be in path)

Description:
The ‘rails’ command creates a new Rails application with a default
directory structure and configuration at the path you specify.

Example:
rails ~/Code/Ruby/weblog

This generates a skeletal Rails installation in ~/Code/Ruby/

weblog.
See the README in the newly created application to get going.
