Nothing to merge; quitting. I noticed that this happens after installing and uninstalling steam or wine. When installed on many packages the use abi_x86_32 is enabled. After deletion, this use is disabled. After rebuilding the world, the problem described above occurs.
Probably related to bug 215242.
Hi, I went through this about a year ago on one of my systems after purging Wine. If you've removed abi_x86_32 and are expecting those 32-bit libraries to be cleaned up, then this is bug 652382. There is a dependency cycle between the 32-bit libraries: libharfbuzz.so.0.50100.0 and libfreetype.so.6.18.3 depend on each other. Portage is currently unable to clean this up. You can work around that by explicitly rebuilding 32-bit freetype without the harfbuzz dependency, which will break the cycle. Use something like: # ABI_X86=32 USE=-harfbuzz emerge -av1 media-libs/freetype I can't recall if I had to emerge any other packages after that for Portage to remove the preserved libs, but I don't think I did.
