The tiff debian tarball URL has disappeared (since debian updated their current
version), which renders this package unbuildable.
Change it to a debian snapshot URL, which should be around indefinitely.
mariadb.org appears to have changed their URL schemes, and the tarball URL used
by this derivation no longer works, which makes this unbuildable from scratch.
This change updates that URL to a mariadb.org location that will still serve
this tarball.
Hash is unchanged.
The existing URL has gone dark; this commit adds one from fedoraproject.org
that still works. We put the new mirror first since ed is in the bootstrap
path, and 16.09 bootstrap doesn't try later URLs.
The 16.09-nixpkgs source tarball Imagemagick-6.9.6-7.tar.xz source tarball is
not available on any of the existing mirrors. We here add one that has it.
As of right now, rogue.rogueforge.net has been down for at least several hours
(likely more).
We add two mirrors here which are likely to be more reliable. We keep the
original download location as a fallback, in case that estimate turns out to be
incorrect.
This is a fix for the current package source file
http://www.greenwoodsoftware.com/less/less-483.tar.gz
not being available anymore.
We bump the less version back to 481, and adjust the source package hash
accordingly. This is a (slight) downgrade from 483 as opposed to an
upgrade since
a) 481 is the current Recommended version by http://www.greenwoodsoftware.com/less/download.html
b) Upstream is unreliable about keeping experimental versions around.
