Running "port livecheck libpng" reports that libpng has been updated.[BR]] For some reason MacPorts seems to be sticking to the "previous" rather than "current" series of libpng releases, so the livecheck result of 1.4.0 rather than 1.2.xx is a little misleading.[[BR]] If/when libpng is updated to 1.2.42 (the most current version), please improve the livecheck expression to look for releases in the correct release series.

New description: Running "port livecheck libpng" reports that libpng has been updated.[[BR]] For some reason MacPorts seems to be sticking to the "previous" rather than "current" series of libpng releases, so the livecheck result of 1.4.0 rather than 1.2.xx is a little misleading.[[BR]] If/when libpng is updated to 1.2.42 (the most current version), please improve the livecheck expression to look for releases in the correct release series. -- Comment(by blb@…): I'm guessing the update (from the [http://www.libpng.org/pub/png/src/libpng-1.4.0-README.txt ReadMe]) Enabled iTXt support (changes png_struct, thus requires so-number change) means all dependents will need a rev-bump, like for jpeg. -- Ticket URL: <http://trac.macports.org/ticket/23125#comment:2> MacPorts <http://www.macports.org/> Ports system for Mac OS

But I don't see ''how'' to do this. Also I'm guessing the two versions would have to be built separately, with two separate configure and make invocations, complicating things (though not insurmountably; we've done that before, e.g. in php5 port and the php5extension and muniversal portgroups). -- Ticket URL: <http://trac.macports.org/ticket/23125#comment:6> MacPorts <http://www.macports.org/> Ports system for Mac OS

Also removes muniversal because it is doing nothing useful (the configured source for each arch does not differ at all apart from the arch flags). -- Ticket URL: <http://trac.macports.org/ticket/23125#comment:8> MacPorts <http://www.macports.org/> Ports system for Mac OS
