path problems

%>rails expense /usr/local/bin/rails:19: undefined method `bin_path' for Gem:Module (NoMethodError).

I keep getting the above error after installing rails. I have gone through every step at hivelogic. It worked once and ever since I have been getting the above error.

I understand the issue is that the path is not configured properly.... on typing echo $PATH i get: /bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/bin:/sbin:/usr/bin:/usr/sbin

but when I execute <prompt%>. ~/.bash_login, on typing echo $PATH i get:


help would be much appreciated.
