Yes, cloning a MacPorts installation from one machine to another is not advisable unless both machines are running the same version of Mac OS X and have the same processor architecture.

You are welcome to do so but if your only goal is to remove the MacPorts installation cloned from the other machine, you can just remove the directories you copied in order to clone it. Or you can follow the MacPorts uninstall instructions in the guide:

Not sure what you're referring to... The apache2 port has never been related to database ports like mysql5 and postgresql84; they have nothing to do with one another and have always been installed separately.

We have some of this documented in the wiki:

http://trac.macports.org/wiki/howto/MAMP

I have not read this document recently so I don't know how up-to-date or accurate it is. If you find inaccuracies, please let us know or log in and fix it directly.


> Last time through (a bit over a year ago) I had to install Apache, then MySQL5 +server, then PHP5 +MySQL +Apache2, then tweak the php config file to include mysql, uninstall PHP, then reinstall  PHP5 +MySQL +Apache2.  Is that no longer the case?  Does the install order matter?

mysql5's +server variant is gone; you now use the separate mysql5-server port if you want to run a MySQL server.

php5's +mysql5 variant is gone; you now use the separate php5-mysql port. (It has variants for selecting the method of interacting with the MySQL server but the default +mysqlnd should be fine.)

I don't know what you had to change in the php config file to make MySQL work before. When installing php5-mysql today, you should receive a message advising you what you need to change in php.ini to make it work.

I can't imagine a reason why you would have had to uninstall php5 then reinstall it. If you believe you are in need of that again, please let us know what you're experiencing so we can know what's wrong.

I do not know; I have never used it. I know that it too has separate ports: postgresql84 if you want the client libraries, postgresql84-server if you also want to run a PostgreSQL server. And if you want PHP to be able to talk to PostgreSQL databases, then you want the php5-postgresql port. (It has variants for selecting the PostgreSQL version but the default +postgresql84 should be fine for you.)

Various php5 features are no longer installed by default, and are instead in separate ports. PHP's gd support is for example now in the php5-gd port. PHP can use ImageMagick via the php5-imagick port. "port echo name:php5-" will show you the other ports that are available.
