Well, you're going to want to install php5 with the +apache2 variant  
(among others). In this case, MacPorts will make sure apache2 is  
installed first.

Support for variant descriptions is in MacPorts, but only for about  
the past week, so they're not available for many ports yet. They  
would be printed by `port variants`, but I don't see anything for the  
ports you want.

I think apache2 should be OK with the default setup. For mysql5 and  
postgresql, you will need the +server variant; this seems to trip a  
lot of people up when they install just the client libraries.  
Postgresql seems to have bindings for Perl, Java, and Tcl; add any  
needed.

php5 is where you're going to have the most choices, variant-wise.  
You definitely want +apache2 +postgresql +mysql5 but there are plenty  
of other variants. Mainly, the others map to configure options, so  
either you could guess from the names of variants (mostly descriptive  
enough) or you could try reading the portfile (it's at `port file  
php5`). You *don't* want +macosx, which will build php for the  
Apple's server, rather than MacPorts'.

The first four you don't need to worry about. +universal will attempt  
to build universal binaries which work on both PowerPC and Intel. The  
next three are platforms, which are detected automatically and can be  
effectively ignored.

+openldap I believe has to do with authentication; the MPMs deal with  
particular ways to do process management. If you don't know what they  
are, you don't need them.

+no_startupitem would avoid installing the relevant launchd script  
to /Library/LaunchDaemons. Again, I don't see any reason you would  
need this.
