If you start building and installing stuff manually it's just as easy to screw
up a linux install. Linux tends not to suffer so much because:
(a) Most linux users don't have administrator privileges, so scrogging the
whole system takes deliberate effort. Windows users tends to everything as an
admin user so it's near impossible to stop installers stomping all over your
system.
(b) Linux tends to come as part of a distribution which includes most[1] the
software you want prepackaged, if not preinstalled. On windows everything
uses third party installers, many of which are poorly written.
It's also much more common to be able to install a program in ~/foo as a
normal user, then blow away the whole directory once you're done.
After building and installing something from source people often ask "how do I
uninstall this". The answer is you don't. You either user a proper package
management system (eg. dpkg or rpm) or you install in a separate directory
and "uninstall" with rm -rf.

use.
