Assuming you're on amd64... These are 32-bit libraries. You probably
had abi_x86_32 set on these packages before, and it's not any more.
Normally Portage will remove these if no other (32-bit) package
requires them, but nowadays there is the
freetype[harfbuzz] -> harfbuzz -> freetype
dependency cycle, so you need to explicitly break the cycle *while
temporarily reenabling 32-bit* to get Portage to remove the libs
cleanly. Something like, temporarily put this in package.use:
app-arch/bzip2 abi_x86_32
dev-libs/glib abi_x86_32
dev-libs/libpcre2 abi_x86_32
media-gfx/graphite2 abi_x86_32
media-libs/freetype abi_x86_32 -harfbuzz # Break the cycle.
media-libs/harfbuzz abi_x86_32
media-libs/libpng abi_x86_32
sys-libs/zlib abi_x86_32
and reemerge these packages. Then when you remove these USE flags and
emerge again, the 32-bit libraries will disappear.
Cheers,
