The port-rdeps script provides that list. http://trac.macports.org/browser/contrib/port-rdeps/ Unfortunately nobody has yet created a port for that script, so it must be installed manually. Here is the output of "port-rdeps -r php5-mcrypt" on my system: Dependencies of php5-mcrypt: php5 gsed gettext libiconv gperf ncurses ncursesw expat libtool automake perl5 perl5.8 autoconf m4 help2man p5-locale-gettext libxml2 zlib bzip2 mhash pcre readline apache2 apr apr-util db46 sqlite3 openssl pkgconfig autoconf213 gawk libmcrypt As of MacPorts 1.8.0, probably the easiest way to install php5-mcrypt universal when some of its dependencies aren't installed universal is as follows: 1. Install php5-mcrypt non-universal: sudo port install php5-mcrypt 2. Upgrade php5-mcrypt and any necessary dependencies to universal: sudo port upgrade --enforce-variants php5-mcrypt +universal > I am a little confused with this: > $port dependents php5-mcrypt > php5-mcrypt has no dependents! > > But the Portfile shows: > depends_lib-append port:libmcrypt \ > port:libtool Correct: php5-mcrypt has no dependents (ports that depend on php5-mcrypt) but it has dependencies (ports php5-mcrypt depends on). You can see the latter with: port deps php5-mcrypt Dependents and dependencies are different (opposite) things. > Is it a good idea to maybe just adjust my conf file for MacPorts to just > built everything as a 4way UB? There's probably no reason to build 4-way universal, and not all ports will support it; particularly ports using the muniversal portgroup often have trouble cross-compiling. If you're on Intel, there's probably no need to build for PowerPC and vice versa. On Snow Leopard there is a good reason to build 2-way universal for x86_64 and i386 because ports build 64-bit by default but some ports can only be built 32-bit so the only way to use both kinds in the same prefix is to install as many ports as possible 2-way universal. On Leopard which builds 32-bit by default it can still be advantageous to build 2-way x86_64 i386 universal because 64-bit software on Intel can be faster and can address more memory. > Where can I read more about how to do this?

MacPorts provides a universal variant automatically for all ports that don't request otherwise. It may not work in all ports. Ports in which it does not work should use "universal_variant no" to turn it off, or override the universal variant and make it work. Some portgroups provide their own universal variants, like the cmake and xcode portgroups. Your port memtester uses "use_configure no"; the default universal variant assumes configure-based programs, so if you turn off the configure phase, MacPorts turns off the universal variant automatically; see: http://trac.macports.org/ticket/12170 As to why php5-mcrypt has a debug variant, that's added by the php5extension portgroup; for why, see: http://trac.macports.org/ticket/22662 _______________________________________________ macports-users mailing list [email protected] http://lists.macosforge.org/mailman/listinfo.cgi/macports-users
