Description Marco Nelissen 2007-01-07 23:37:22 UTC

I can't emerge faad2, because the latest version of faad2 depends on libmp4v2, which in turn depends on an older version of faad2, which is blocked:

~ # emerge -pv faad2

These are the packages that would be merged, in order:

Calculating dependencies... done!
[blocks B     ] <media-libs/faad2-2.0-r9 (is blocking media-libs/libmp4v2-1.4.1)
[ebuild  N    ] media-libs/libmp4v2-1.4.1  4,678 kB
[ebuild     U ] media-libs/faad2-2.0-r11 [2.0-r3] USE="(-xmms%)" 8 kB

Total size of downloads: 4,687 kB

~ # emerge faad2

!!! Error: the <media-libs/faad2-2.0-r9 package conflicts with another package;
!!!        the two packages cannot be installed on the same system together.
!!!        Please use 'emerge --pretend' to determine blockers.

For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):
