I don't use Macs, but web searching suggests an answer. Apparently, there is no command-line switch to disable generation of ._ psuedofiles in tarballs, but there is an undocumented environment variable that so modifies tar behavior, COPY_EXTENDED_ATTRIBUTES_DISABLE=true. For reasons unknown outside the bowels of One Infinite Loop, this was renamed to the far-less-appropriate COPYFILE_DISABLE as of the Leopard release of Mac OS X. [1] When the build triplet matches *-apple-darwin*, Automake could include in the distdir target code to set both of the undocumented environment variables to true. That presumes no Automake clients find the extended attributes and resource forks in tarballs valuable. Cheers, Dave Hart [1] http://norman.walsh.name/2008/02/22/tar
