In case an ICD, devel/ocl-icd, is installed, port devel/clinfo fails with : CommandLine Error: Option 'enable-value-profiling' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options
See also Bug 219562 .
I'm not sure what to do with this, as it seems like a bug in llvm rather than ocl-icd or clinfo.
I cannot reproduce this error, is this still relevant?
