- get new version from: http://packages.qa.debian.org/m/mpack.html (files: mpack_1.6.orig.tar.gz, mpack_1.6-4.diff.gz, mpack_1.6-4.dsc) and apply patch 'mpack_1.6-4.diff' to original dir: mpack_1.6/ - this fix the MD5 coding on 64.bit platforms (well, seems to). - added in Contrib to allow separate test (since building mpack seems fishy)
