How install gcc with deb

[Robert Heller]

If the OP has access to a networked machine running the same version of 
Ubuntu, it is possible to use "apt-get install -d ..." to populate 
networked machine's /var/cache/apt/archives and then use a "sneaker net" to 
populate the non-networked machine's /var/cache/apt/archives and then do an 
"apt-get install ..."  Apt-get will then use the already downloaded files 
without needing to access the networ.

Another option would be to use (large) removable drive as a mirror, populating 
with debmirror on a networked machine and transporting the removable drive to 
the non networked machine and suitably hacking the list files in 
/etc/apt/lists...  I don't know if you need to actually install apache on the 
off-line machine (the URLs then become localhost://ubuntu...) or if you can 
use URLs like file:///mirrordrive/ubuntu... -- I do this for some Ubuntu VMs 
on my CentOS 6 host, which already has apache installed for web development 
work.
