/bin/sh: yacc: command not found

You are probably missing:
BuildRequires: byacc

I saw that, and have bison as a BuildRequires. I thought I'd test it to make sure, but the mockbuild succeeded.

bison does not provide a "yacc" binary though, so you'd need to patch to use that.

The reason it worked in your mockbuild could be that the parallelism from %{_smp_mflags} was lower. It may be a bug in the Makefile such that this package is not safe to build with %{_smp_mflags}, or just that the increased parallelism makes it think it needs to regenerate some files where it doesn't really need to.

My mock build completed now using mock-1.0.0-1.fc12.
