Even compiling from the source is not very difficult, most of the software uses autoconf/automake....

$ tar -xvzf package-1.2.3.tar.gz && cd package-1.2.3 && ./configure && make && sudo make install && cd .. && rm -rf package-1.2.3

A single command line does it all :) (Haven't used this kind of thing in years, but it's unforgettable)

I still love the way it automatically downloads and updates ALL the packages, and upgrade for the whole distro in Ubuntu (every 6 months), click, wait a few hours, upgraded.
