Installing Opera from tarball without sudo priviledges

The online documentation in the Opera KB says to use

--prefix= to install everything to .

. That however is not enough I find, as the script won't create the necessary directories. Hobo solution: Check the error log from the install script and create them by hand.

PS: If you use Gnome (or at the very least gnome-terminal), don't forget to change the default browser in gnome-control-center (I tried the gconftool way first, but no dice).
