Comment (by ryandesign at 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/

 }}}

 But this doesn't:
