Michael already posted the "correct answer", and that's what I'm slowly
migrating towards, myself.

But the best way I've found before that was install it in a specific
subtree of my ~ (that way I don't need root at any time), and manage
PATH semi-automatically, as follows:

1. make a symlink in ~/bin to each subdirectory containing programs.
For example, if I install foopkg in ~/foopkg/ and the foo program is
~/foopkg/bin/foo , I symlink ~/bin/foopkg -> ../foopkg/bin .

2. this snippet very early in my .bashrc adds each such subdirectory to
the PATH:

case $PATH in
    (*/rc-scripts*)
        :
        ;;
    (*)
        PATH=$PATH:$( find ~/bin -type l -xtype d | paste -sd: )
        ;;
esac

The first case is there to prevent recursion, as I know that rc-scripts
will always be one of the symlinks.
