$ cd MacPorts - 2.7 .2 /
$. / configure
$ make
$ sudo make installPick a location to store a working copy of the MacPorts code. For this example,
/opt/mports will be used, but you can put the source anywhere. This example
will create /opt/mports/macports-base containing everything needed for
MacPorts.
$ mkdir - p / opt / mports $ cd / opt / mports $ git clone https: //github.com/macports/macports-base.git $ cd macports - base $ git checkout v2 .7 .2 # skip this if you want to use the development version
MacPorts uses autoconf and makefiles for installation. These commands will build and install
MacPorts to /opt/local. You can add --prefix to
./configure to relocate MacPorts to another directory if needed.
$ cd / opt / mports / macports - base $. / configure--enable - readline $ make $ sudo make install $ make distclean
