bsd.port.mk rev. 1.304 for details on the change.
The fix here is one of the following.
(1) Define USE_BZIP2 instead of BUILD_DEPENDS on bzip2 and redefining
EXTRACT_* commands.
(2) Change ${EXTRACT_CMD} to ${TAR} when the command is obviously
calling the "tar" command (i.e., arguments like "-xzf" are spelled
out).
(3) If ${EXTRACT_CMD} is called directly with ${EXTRACT_BEFORE_ARGS},
add ${EXTRACT_AFTER_ARGS} to the command line as well.
(4) If any of EXTRACT_CMD, EXTRACT_BEFORE_ARGS or EXTRACT_AFTER_ARGS
is set, define the other two too.
will be expanded multiple times if ${MASTER_SITE_SUBDIR} contains
more than one item.

(2) Replace stale site with a good one in MASTER_SITE_GNU.

(3) Add new variable USE_BZIP2, which, like USE_GMAKE, will change the
default decompression method of distfiles from gzip to bzip2.
Since tar doesn't have a simple flag to turn on bzip2
decompression, I changed the way EXTRACT_CMD and
EXTRACT_{BEFORE,AFTER}_ARGS work. These are the new defaults:
EXTRACT_CMD: gzip or bzip2
EXTRACT_BEFORE_ARGS: -dc
EXTRACT_AFTER_ARGS: | tar -xf -
(They used to be "tar", "-xzf", and "", respectively, before.)
Also, EXTRACT_SUFX will default to ".tar.bz2" if USE_BZIP2 is set.
There are a few things porters should be careful about:
(a) If you are using bsd.port.{pre,post}.mk, USE_BZIP2 should be set
before the .include of pre.mk.
(b) Do not use ${EXTRACT_SUFX} as an alias of tar. There is a new
variable ${TAR} for that purpose.
(c) If you are calling ${EXTRACT_CMD} directly, you need both
${EXTRACT_BEFORE_ARGS} and ${EXTRACT_AFTER_ARGS} in the command
line. (The latter was previously empty so could be omitted --
that is no longer the case.)
(d) If you need to set any of EXTRACT_CMD, EXTRACT_BEFORE_ARGS or
EXTRACT_AFTER_ARGS, define all three, even if they are the
default. The values of these variables may very well change in
the future (but the calling syntax probably will not) so it will
save the port from breakage when that happens.
Tested by: recompiling the entire ports tree
