Portage is a package management system used by Gentoo Linux. Gentoo is sometimes referred to as a meta-distribution due to the extreme flexibility of Portage, which even makes it operating-system-independent. Sabayon Linux is based on Gentoo, but is a bit different in a few ways. Portage is not the default package manager for Sabayon and should only be used by those that are highly experienced with Gentoo. Sabayon Linux Entropy Server uses Portage to bring you the binary packages, making your life much simpler.

This page is to separate Portage HowTo articles from Entropy HowTo articles. If you have a HowTo article for Portage, please add it here.

The Portage package manager is not the default package manager of Sabayon. It should only be used by advanced users who understand the Portage system and understand what flags can do to a system. If you insist on using Portage and you FUBAR your Sabayon Linux installation, you are on your own. This is your big warning, so pay attention to it.


Portage errors, blocks, output problems

"USE-flag vdpau" blocks VLC media player

When upgrading VLC media player with Portage to the latest version, you may find some errors and blocks

that you just don't seem to get solved. VLC seems impossible to upgrade.

The problem is that the portage-output is not pointing you in the right direction.

The REAL blocker here, is that the USE-flag "vdpau" is enabled on vlc.

Because of that you cannot install <media-video/libav-9.11

vdpau is incompatible with libav. Removing vdpau from the USE flags removes the block and vlc will emerge fine.

So, to sole, or bypass this, edit:


scroll down to the media-video/vlc entry, and add the -vdpau USE-flag

THEN just emerge the package as you normally would do.

This is actually a known bug at Gentoo: Bug 489922)

NVidia blocks Chromium

Users with NVidia-drivers installed, who wants to emerge/upgrade chromium, will notice that the package prevents chromium

for being emerged. This is because the "tcmalloc USE-flag" is enabled on chromium.

So, to solve, or bypass this., edit:


scroll down to the www-client/chromium entry, and add the -tcmalloc USE-flag

THEN just emerge the package as you normally would do.
