BibTool: checksum mismatch due to misconfigured server

[ryandesign (Ryan Carsten Schmidt)]

The BibTool port fails to fetch properly:

The non-matching file appears to be HTML. See this page for possible reasons
for the checksum mismatch:

The reason is that upstream has updated the software to a new version and removed the old file ​http://tug.ctan.org/tex-archive/biblio/bibtex/utils/bibtool/BibTool-2.48.tar.gz. When you request the old file, you get a page that says "Note: you requested the material at a path /biblio/bibtex/utils/bibtool/BibTool-2.48.tar.gz that doesn't exist. This is the closest directory".

Upstream should not remove old distfiles, and upstream should return a proper 404 error code when requested URLs do not exist. Not doing so causes problems for MacPorts, as you can see. Please report these issues to upstream.

I'll submit a separate ticket to request this port be updated to the latest version, but that will only temporarily hide this problem (until a new version is released), so these issues do still need to be fixed upstream.

I have sent email to ctan at dante.de explaining these matters.

Fixed in r98322 by removing tug.ctan.org http server from master_sites.
