what is the difference between 2 types of rails installation


I would like to know the difference between installing the rails

1. gem install rails and 2. copying the rails package from the "http://rubyforge.org/frs/? group_id=307"

For some unknown reason, in my system the command "gem install rails" taking too much time(i waited for about 2 Hours, I hope no software is taking this much time)

What is the minimum system configuration needed? My system has 128MB RAM, does it matter when running the command "gem install rails"?

So I copy the rails package from ruby forge.

But I am getting Routing Error when I run http://127.0.01:3000/MyTest

Thanks Ram

I think having less than 1 Gig of RAM on WIndows, linux or OS X is going to be very limiting, especially when you compile native libraries like ImageMagick
