    @${ECHO_MSG}
    @${ECHO_MSG} Instead of installing the port, which will take a considerable amount of
    @${ECHO_MSG} extra time and space, you can instead type \"make build\".  Then you can move
    @${ECHO_MSG} work/${PORTNAME}-${PORTVERSION} to wherever you like, and run sage from there.
    @${ECHO_MSG} However, there is no guarantee that this alternative will always work.
