After running emerge --depclean recently, I got the following message. !!! existing preserved libs: >>> package: media-libs/opus-1.1 * - /usr/lib64/libopus.so.0 * - /usr/lib64/libopus.so.0.5.0 * used by /usr/lib64/libspice-server.so.1.9.0 (app-emulation/spice-0.12.5)
Found this in spice-common/configure.ac: PKG_CHECK_MODULES([OPUS], [opus >= 0.9.14], have_opus=yes, have_opus=no) AM_CONDITIONAL([HAVE_OPUS], [test "x$have_opus" = "xyes"]) AM_COND_IF([HAVE_OPUS], AC_DEFINE([HAVE_OPUS], 1, [Define if we have Opus]))
fixed in app-emulation/spice-0.12.5-r1 and net-misc/spice-gtk-0.25-r1 by unconditionally depending on media-libs/opus.
