Now that someone has removed the python-fchksum-1.6.1 ebuild and there is a line in package.mask that masks python-fchksum-1.6.1-r1, there are no ebuilds left for for portage to depend on. I assume that anyone attempting to install gentoo would run into a problem running "emerge -u system". I get the following error if I use the --deep flag on my already-installed system: % emerge -vup --deep world These are the packages that I would merge, in order: Calculating world dependencies \ !!! all ebuilds that could satisfy "dev-python/python-fchksum" have been masked. !!! (dependency required by "sys-apps/portage-2.0.47-r10" [ebuild]) !!! Problem with ebuild sys-apps/man-pages-1.56 !!! Possibly a DEPEND/*DEPEND problem. !!! Depgraph creation failed.
Someone has fixed this by removing the line from package.mask that was masking dev-python/python-fchksum-1.6.1-r1.
