Hello Since stsci-distutils has a zip file for SRC_URI, it should depend on unzip. There are various other similar bug reports around and IMO portage/emerge could add the dependency automatically, as it also chooses to use unzip to extract the zip source by itself (how should the ebuild know which tool emerge will pick). Off course this applies to all other decompressors too (could also include compressed patches etc). Anyway, for now adding the dependency to the ebuild seems to be the easy fix. And for documentation, to fix this simply emerge -av app-arch/unzip Best regards Marcel Greter
