Created attachment 620742 [details] output from emerge --info The ebuild doesn't flake out, but still says fatal: -- Looking for os_signpost_interval_begin - not found -- Found PythonInterp: /var/tmp/portage/sys-devel/llvm-11.0.0.9999/temp/python3.6/bin/python (found version "3.6.10") -- Constructing LLVMBuild project information -- Found Git: /usr/bin/git (found version "2.24.1") fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.

=llvm-10.0.0.9999 does have the same fatal warning in it's src_configure, but nothing of the additional stuff that I just posted. The non-live snapshot of =llvm-10.0.0_rc4 is free of this.
Given that four weeks have passed without reaction, this error is most likely to be benign.
