As you see in the code this is linux only: CLOCK_MONOTONIC, HW_CPUSPEED, -soname, -rpath, linux/perf_events.h,

Even on linux it would fail: sort.c:386:21: error: always_inline function '_mm256_loadu_si256' requires target feature 'sse4.2', but would be inlined into function 'djbsort_int32' that is compiled without support for 'sse4.2'

-march=native or -msse4.2 would be needed.
