Why do my pkgsrc-2009Q1 tarballs appear broken?

[Anders Lindgren <ali%df.lth.se@localhost>]

I just updated my i386 box to 5.0_RC4, and sucked down pkgsrc-2009Q1 to 
update my packages.

With both the .bz2 and the .gz tarballs (both of which match the 
fingerprints on ftp.netbsd.org after download), I get:

tar: Invalid header, starting valid header search.
tar: Invalid header, starting valid header search.
tar: Invalid header, starting valid header search.

during extraction/test of the archives.

Testing the archives with tar -tzf pkgsrc-2009Q1.tar.gz 2>&1 gives
(assuming this does get the stdio buffering right) that this happens 
between:

pkgsrc/devel/vanessa_logger/distinfo
tar: Invalid header, starting valid header search.
pkgsrc/mail/bulk_mailer/README.html
tar: Invalid header, starting valid header search.
pkgsrc/devel/vanessa_socket/patches

(notice the funny filename ordering) and the last one at:

pkgsrc/editors/joe/CVS/Tag
tar: Invalid header, starting valid header search.
pkgsrc/editors/joe/patches/patch-aa

I'm all ears for ideas. :-)
