Looks like the llvm38 port didn't build the libclang_rt libraries. These are needed for the sanitizers, and so on. The llvm37 port does have these: % ls -l llvm37/lib/clang/3.7.1/lib/freebsd total 4188 -rw-r--r-- 1 root wheel 2083354 2016-07-12 05:08:14 libclang_rt.asan-i386.a -rwxr-xr-x 1 root wheel 705264 2016-07-12 05:09:27 libclang_rt.asan-i386.so* -rw-r--r-- 1 root wheel 1620 2016-07-12 05:08:06 libclang_rt.asan-preinit-i386.a -rw-r--r-- 1 root wheel 35914 2016-07-12 05:08:12 libclang_rt.asan_cxx-i386.a -rw-r--r-- 1 root wheel 120524 2016-07-12 05:08:18 libclang_rt.builtins-i386.a -rw-r--r-- 1 root wheel 33904 2016-07-12 05:08:19 libclang_rt.profile-i386.a -rw-r--r-- 1 root wheel 417872 2016-07-12 05:08:19 libclang_rt.safestack-i386.a -rw-r--r-- 1 root wheel 659270 2016-07-12 05:08:02 libclang_rt.ubsan_standalone-i386.a -rw-r--r-- 1 root wheel 21234 2016-07-12 05:08:02 libclang_rt.ubsan_standalone_cxx-i386.a -Dimitry
