Comment (by ryandesign@macports.org):

 This works:

 {{{
 $ port info zlib
 zlib @1.2.3, Revision 1 (archivers)
 Variants:    examples, (+)universal

 zlib is designed to be a free, general-purpose, legally unencumbered,
 lossless data-compression
 library for use on virtually any computer hardware and operating system.
 Homepage:    http://www.zlib.net/

 Platforms: darwin, freebsd
 Maintainers: landonf@macports.org ryandesign@macports.org
 openmaintainer@macports.org
 $
 }}}

 But this doesn't:

 {{{
