The vigra homepage has been moved to github (see URL above). It the old URLs are still forwarded to the new location, but the Download-Links to the old releases had to be changed to circumvent this forwarding. Reproducible: Always Steps to Reproduce: 1. clean up downloaded vigra files from /usr/portage/distfiles 2. Try to emerge some of the available vigra versions (<= 1.9.0) Actual Results: Fetch fails since old locations no longer exists. Expected Results: Ebuilds should use the new links presented at the website. Old URL: http://hci.iwr.uni-heidelberg.de/vigra/vigra-1.9.0-src.tar.gz New URL: http://hci.iwr.uni-heidelberg.de/vigra-old-versions/vigra-1.9.0-src.tar.gz Just replace SRC_URI="http://hci.iwr.uni-heidelberg.de/${PN}/${MY_P}.tar.gz" by SRC_URI="http://hci.iwr.uni-heidelberg.de/${PN}-old-versions/${MY_P}.tar.gz" within the version <= 1.9.0 ebuilds.
The file is present on the mirrors, no need to clutter up the changelog.
