Created attachment 394034 [details, diff] fix darwin dynamic lib install name mangling sys-devel/llvm-3.5.0 will fail to install with a QA warning that $EPREFIX/usr/lib/clang/3.5.0/lib/darwin/libclang_rt.asan_iossim_dynamic.dylib uses an invalid self reference. Also it installs a libLTO.dylib that references @rpath/libLLVM-3.5.dylib and thus fails to find it. The attached patch fixes both. BTW: Note grep reporting "grep: configure: No such file or directory" in the output below. grepping for PACKAGE_VERSION in configure does not work because a separete BUILD_DIR is used. It doesn't cause problems though since $PV and configure:PACKAGE_VERSON have identical values. Maybe "${S}"/configure should be used instead? The former error shows as follows: # CC=clang CXX="clang++ -stdlib=libc++" emerge -1 llvm Calculating dependencies... done! >>> Verifying ebuild manifests >>> Running pre-merge checks for sys-devel/llvm-3.5.0 * Checking for at least 1200 MiB disk space at "/usr/local/gentoo/var/tmp/portage/sys-devel/llvm-3.5.0/temp" ...

Created attachment 394074 [details, diff] fix darwin dynamic lib install name mangling The previous patch introduced a new problem. This one fixes that and updates the ebuild for 3.4.2 as well which has the same problems.
Created attachment 394602 [details, diff] updated patch to fix darwin dynamic lib install name mangling also for 3.5.1
Thanks, I applied your patch
