After building dev-lang/rust-bin, I see a number of shared objects listed under /var/db/pkg/dev-lang/rust-bin-1.1.0/REQUIRES that aren't actually exported to the system: x86_64: librustc_resolve-7d23ff90.so x86_64: libgraphviz-7d23ff90.so x86_64: librustc_borrowck-7d23ff90.so x86_64: libflate-7d23ff90.so x86_64: libfmt_macros-7d23ff90.so x86_64: libtest-7d23ff90.so x86_64: librustc_lint-7d23ff90.so x86_64: libgetopts-7d23ff90.so x86_64: libstd-7d23ff90.so x86_64: librustc_data_structures-7d23ff90.so x86_64: librustc_back-7d23ff90.so x86_64: librustc-7d23ff90.so x86_64: libsyntax-7d23ff90.so x86_64: librustc_llvm-7d23ff90.so x86_64: librustc_trans-7d23ff90.so x86_64: librustc_privacy-7d23ff90.so x86_64: librustc_driver-7d23ff90.so x86_64: libterm-7d23ff90.so x86_64: librustdoc-7d23ff90.so x86_64: libserialize-7d23ff90.so x86_64: librbml-7d23ff90.so x86_64: liblog-7d23ff90.so x86_64: librustc_typeck-7d23ff90.so My understand is that this is due to these objects not specifying SONAME. For example: $ scanelf --soname /opt/rust-bin-1.1.0/lib/librustc_resolve-7d23ff90.so TYPE SONAME FILE ET_DYN /opt/rust-bin-1.1.0/lib/librustc_resolve-7d23ff90.so vs $ scanelf --soname /usr/lib/libc-2.20.so TYPE SONAME FILE ET_DYN libc.so.6 /usr/lib/libc-2.20.so I believe REQUIRES_EXCLUDE will need to include this list of libraries since it doesn't look like these should be exported.

Thanks for reporting, I'll have a look at this when I'll have time.
It seem like 1.1.0 is no longer in Gentoo. Could you check if 1.2.0 or later are affected by this issue, too? Thanks!
I'm still seeing this with 1.5.0: for line in $(< /var/db/pkg/dev-lang/rust-bin-1.5.0/REQUIRES); do echo $line | grep 35c36e89; done libflate-35c36e89.so libfmt_macros-35c36e89.so libgetopts-35c36e89.so libgraphviz-35c36e89.so liblog-35c36e89.so librbml-35c36e89.so librustc-35c36e89.so librustc_back-35c36e89.so librustc_borrowck-35c36e89.so librustc_data_structures-35c36e89.so librustc_driver-35c36e89.so librustc_front-35c36e89.so librustc_lint-35c36e89.so librustc_llvm-35c36e89.so librustc_mir-35c36e89.so librustc_platform_intrinsics-35c36e89.so librustc_privacy-35c36e89.so librustc_resolve-35c36e89.so librustc_trans-35c36e89.so librustc_typeck-35c36e89.so librustdoc-35c36e89.so libserialize-35c36e89.so libstd-35c36e89.so libsyntax-35c36e89.so libterm-35c36e89.so libtest-35c36e89.so
