thanks for your help, but I'm out of my depth. Can I be sure that my chip is
indeed x86-64? How can I "check the zlib port"? I did
port info zlib
and got

zlib @1.2.5 (archivers)
Variants:             universal

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

Platforms:            darwin, freebsd
License:              zlib
Maintainers:          landonf at, ryandesign at,
                      openmaintainer at

Is this the only version of zlib available on MacPorts? How can I get hold
of a version of zlib that will work with my chip's instruction set?
