I just upgraded from a PowerBook to a MacBook Pro. The migration
assistant tool kept my old macports system intact. I can still run all
of the ports I had installed; particularly, I can still use TeXmacs
and teTeX. However, I had built all of my ports as PPC binaries, so
they are running via Rosetta. This also means I can't update any of my
ports because port fails to recognize the architecture. Since there
have been so many posts lately about things failing to build on 10.5,
I'm a little scared to wipe my old macports system and rebuild from
scratch. I particularly can't afford to be without a LaTeX environment
right now.
So, is there any way I can "jail" a new installation of macports? If I
can build everything successfully, I want to be able to delete the old
version and move the new one to the standard location.
You can have multiple installs of MacPorts on a single system.
However, some ports may not work if you change the location of the
installation. So, I would recommend that you move the existing
installation aside (i.e. `sudo mv /opt/local /opt/ppc`) and install a
new one in its place. If you succeed at getting the new one running
sufficiently, you can get rid of the old one; otherwise move the old
one back in place.
In order to quarantine two MacPorts installations, you should build
them from source. The tarballs are available on the Downloads [1]
page. You should ./configure them along the lines of the following:
% ./configure --prefix=/opt/local \
--with-tclpackage=/opt/local/share/macports/Tcl
You can pick something other than /opt/local if you want, but it might
not work to move it back to /opt/local later, should you care. Also,
it's possible that you might get conflicts for files installed in /
Applications/MacPorts or /Library/Frameworks.
The Guide [2] briefly discusses this issue too.
