| Subject: | tar file gives warning messages on Linux |
Installing Code::TidyAll gets odd messages from tar on Ubuntu 13.04:
--> Working on J/JS/JSWARTZ/Code-TidyAll-0.18.tar.gz
Fetching http://www.cpan.org/authors/id/J/JS/JSWARTZ/Code-TidyAll-0.18.tar.gz ... OK
/bin/tar: Ignoring unknown extended header keyword `SCHILY.dev'
/bin/tar: Ignoring unknown extended header keyword `SCHILY.ino'
/bin/tar: Ignoring unknown extended header keyword `SCHILY.nlink'
Google searches suggest that this is because the tar file was built on MacOSX and contains tar attributes that are not compatible with Linux. For example:

Here the author rebuilt the tar file on Linux, but apparently installing "gnutar" on MacOSX and using that fixes the issue because the default "tar" is BSD tar....
Not a big deal and it doesn't cause it to fail, just concerning when you first see it.
