here is a sample snippet of the tail of a revdep-rebuild followed by another
one
===
* Messages for package sys-devel/gcc-4.1.2:

* If you have issues with packages unable to locate libstdc++.la,
* then try running 'fix_libtool_files.sh' on the old gcc versions.
* GNU info directory index is up-to-date.
Build finished correctly. Removing temporary files...
You can re-run revdep-rebuild to verify that all libraries and binaries
are fixed. If some inconsistency remains, it can be orphaned file, deep
dependency, binary package or specially evaluated library.

What could i have broken this time? Shouldn't subsequent revdep-rebuilds be
doing nothing? This is my fourth consecutive revdep-rebuild...

I am using overlays. I just recently removed the ecatmur overlay from my
listing, so I didn't think it would be causing problems

* sabayon [Subversion] (source:

* sunrise [Subversion] (source:

/===

The roslin overlay was used primarily for frostwire, i can't remember what
the other two were for. But if it were an overlay issue, wouldn't
revdep-rebuild be saying that it uses the overlays right after the build
list? What could be going on?
