You don't say when your baseline was, but the complexity of resolving the package tree has increased quite a bit over the last year due to new features like automatic rebuilds of consumers after library updates. Another somewhat common cause of sudden slowdowns is how portage resolves conflicts (like packageA requiring an old version of libraryB), which is rather time-consuming. You can try adding --backtrack=3D0 to the emerge command to make it stop and print an error message when encountering a conflict rather than look for a solution. Then you can 'help' out by manually resolving any conflicts by adding package versions to /etc/portage/package.mask . Preferably try this *after* running an update, so your system is up-to-date against your local version of the gentoo tree, otherwise "normal" simple-to-resolve conflicts might cause confusion. ;-) --=20 eroen --Sig_/ivf/EUDgVAvYrZ8mhUnDKqM Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAEBAgAGBQJS5Si0AAoJELSISlJWmwxLv+IIAIXZTzEr1keQNl3fYixzKlOk xjFYMYIDySIBkOASSCdCsC/4rHrbe3WCJD2mP7prSgy/yO5Y/xS+ug5JIEwb8P+1 X/7UbgEkdU1a5sC08+eGayR82LNlu4THJ/FflmKA4GZjdX7NZiMDIPoh7VA9qcl8 TUiVnHUpG5Qs2uABXKYjWQ+hPrhAIctmtT1jvEE4YoZaVVD9Z2SOs3XVUFsHAT36 J9Nnv+kaQo0lfrv3pplXY21yvhGhs4TA6oHPc22EuNuhijz6sd5cKFfEFyvw8anx nMpmH1vXsKCi0GaZYRxbORKNn2iV4uG8m7qoonv0Qp+Egykq3WeTEc8Pfh9yVuM= =DyLU -----END PGP SIGNATURE----- --Sig_/ivf/EUDgVAvYrZ8mhUnDKqM--
