 Installing MacPorts from source will fails with the missing user
 "macports" (it would be great if this would be explained in the install
 documentation), but this can be overwritten with the "--with-macports-
 user" switch for "configure".

 However, using "--with-macports-user=root" will result in the following
 error message when trying to "sudo make install":

    ===> making install in doc
    /usr/bin/install -c -d -o root -g admin -m 0755 /opt/local
    /usr/bin/install -c -d -o root -g admin -m 0755 /opt/local/etc/macports
    < prefix.mtree /usr/sbin/mtree -U -e -p /opt/local > /dev/null
    < base.mtree /usr/sbin/mtree -U -e -p /opt/local > /dev/null
    mtree: line 16: unknown group root
    make[1]: *** [install] Error 1
    make: *** [install] Error 1

 Looking into "./doc/base.mtree" reveals  that "root" is also used as the
 group:

    Preferences uname=root gname=root mode=755

 Changing the "gname" to "admin" solves the problem.
