Configuring search environment for revdep-rebuild
Checking reverse dependencies...
Packages containing binaries and libraries broken by a package update
will be emerged.
Collecting system binaries and libraries... using existing /root/.revdep-rebuild.1_files.
Collecting complete LD_LIBRARY_PATH... using existing /root/.revdep-rebuild.2_ldpath.
Checking dynamic linking consistency... using existing /root/.revdep-rebuild.3_rebuild.
Assigning files to ebuilds... using existing /root/.revdep-rebuild.4_ebuilds.
Evaluating package order... using existing /root/.revdep-rebuild.5_order.
All prepared. Starting rebuild...
emerge --oneshot -p =net-im/gaim-2.0.0_beta3-r2 =media-video/vlc-0.8.4a-r1
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] net-im/gaim-2.0.0_beta3-r2
[ebuild UD] media-video/vlc-0.8.4a-r1 [0.8.5-r5] USE="aac%* -ffmpeg% -joystick%"
Now you can remove -p (or --pretend) from arguments and re-run revdep-rebuild.
