It's only semi-luck that it extracts in 5.x+.

The extract command does gzip -nf -9 -dc Mesa-linux-bin-6.5.tar.bz2
(which silently does nothing) and pipes it to tar.

However, on 5.x+ the tar command is bsdtar by default.  bsdtar looks
into its input and determines that it has been bzip'd and figures out
how to handle it.  The default 4.x tar (gnu tar) does not and needs
the -j arg.

Since you can't have more than one EXTRACT_SUFX, ports with a mix of
.gz & .bz2 need special handling - maybe override do-extract, but the
default do-extract does other stuff that is kludgy to copy/paste into
individual ports.  bsd.ports.mk is a little weak on support for this
kind of thing.

Maybe there could be a pre-extract that handles the .bz2 separately.

As a workaround, check OSVERSION and, for 4.x, could override TAR
to use bsdtar and have a BUILD_DEPENDS on archivers/bsdtar.
