surely enough, I see the same warnings on a 64-bit Linux:
$ tar tf upstream/sagenb-0.11.1.tar | less
tar: Ignoring unknown extended header keyword `LIBARCHIVE.creationtime'
tar: Ignoring unknown extended header keyword `SCHILY.dev'
tar: Ignoring unknown extended header keyword `SCHILY.ino'
....

Probably my tar is newer and thus the install can live with this.
IMHO this tarball should be replaced by something glatt kosher...

Please open a ticket and cc me on it.

no, this is not enough,  as this will surely change the tarball 
checksum; you need to follow the instructions
in sage developer guide to recreate them.

Best,
