--with-macports-user also sets the group

[thomas.c.jansen@…]

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.
