Currently, the package system has an difficalty to handle
multiple distfiles in different places.  We's been discussed
it on tech-pkg-ja@jp.netbsd.org mailing list in these weeks.

Thanks Todd for the good-timing proposal!

Here's the example.

These are three distfiles contain ptex, Japanized version of
TeX, which is not committed main pkgsrc so far.

/pub/TeX/ascii-ptex/ptex218/ptex218.tar.gz
/pub/TeX/ascii-ptex/ptex218/web2c/web-7.2.tar.gz
/pub/TeX/ascii-ptex/ptex218/web2c/web2c-7.2.tar.gz

The files are located in two different directories in master
FTP site, but DISTFILES is basename'ed, so we should specify
MASTER_SITES like shown below.

MSTER_SITES = ftp://ftp.ascii.co.jp/pub/TeX/ascii-ptex/ptex218/ \
ftp://ftp.ascii.co.jp/pub/TeX/ascii-ptex/

But in this definition, make fetch tries 6 URLs to get
distfiles and it is obvious that the half of them will fail.
This is because of these variables are not individually
supplied on each files.

To avoid this problem, the package could be splitted into
two parts (ptex-common, ptex-jis) and the latter depended
the formar.  But make of the latter fails if the formar is
already built/installed since the dependancy is in source
code.

If multiple distfiles are archived/compressed in different
format, similar problem would occur.

Any suggestions?
