You can install Rails in a Fedora system with these commands…

sudo gem update
sudo gem install rails --include-dependencies

If you are getting a ‘Can’t locate CPAN.pm in @INC’ error while opening cpan, you have not installed Bundle::Cpan. You can do that without Cpan – using yum

yum install perl-CPAN

This will install an RPM, and try to resolve all the dependencies for you using your repositories.

To access net on a guest OS installed within VirtualBox, you have to enable bridging. This is what I did…

Run as root

brctl addbr br0
ifconfig eth0 0.0.0.0
brctl addif br0 eth0
ifconfig br0 192.168.1.54 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 br0
route add default gw 192.168.1.1 br0
VBoxTunctl -b -u binnyva
ifconfig tap0 up
brctl addif br0 tap0

Open VirtualBox, select the machine you want and go to the network section. Select ‘Host Interface’ in Attached to and enter ‘tap0’ in Interface name. Now you should be able to get the connection on the guest system.
