1) both libraries are experimental (see ticket ???)
2) Archive;Zip has never work (except with the mode COMPRESSION_STORED)
3) Archive;Tar + Gzip dynamic PMC generate *.tar.gz files, for examples :
  a) with distutils :
       $ parrot setup.pir sdist
  b) the TAP library uses it, so you could generate&upload your smoke
reports to Smolder :
       $ parrot t/harness.pir --archive --send-to-smolder
