    .bashrc is only read for interactive shells. Besides, if which is a bash
    alias as well,

    $ command -v which
    alias which='type -path'
    $

    it will break too,

    $ which which
    $

    I think what you can do is to ignore the value returned by command -v, and
    just use it is an indication that this thing exists. After all, if you can
    find it using command -v, just calling it will work too. Something like

    if command -v gcc272 > /dev/null 2> /dev/null; then echo gcc272; else \
    echo gcc; fi
