The ebuild for procps attempts to download procps_3.3.2-2.debian.tar.gz but the version available for Debian is procps_3.3.2-3.debian.tar.gz Reproducible: Always If the ebuild procps-3.3.2_p2-r1.ebuild is renamed to procps-3.3.2_p3.ebuild, it will work.
err... procps (1:3.3.2-3) unstable; urgency=low * Updated to debhelper compat level 9 * DH9 uses harden build flags Closes: #656511 * Added news entry about toprc file format change Closes: #651213 so nothing we would be intrested in, debian specific changes and the files for 3.3.2_p2 are in gentoo mirrors, if that isn't working, is because wrong settings in make.conf for mirrors then, nothing else
