ports broken?

[Marco S Hyman <marc@snafu.org>]

The ports makefile (version 1.93 in the ports/infrastructure/mk directory)
seems to be broken.  Try to build pgp, for example, and you'll find
that EXTRACT_CMD is no longer set to tar, but to gzip!

sigh... I see what happend.  EXTRACT_CMD is no longer the extract
command, but the uncompress command.  The extract command is now
part of the EXTRACT_AFTER_ARGS

What bullshit.

The following ports are probably broken due the the new makefile changes.
They all reference  EXTRACT_CMD (and expect it to be an extract command,
not a file decompressor) or redefine EXTRACT_CMD and expect EXTRACT_AFTER_ARGS
to be blank.
