module-build is not missing the dependency; read the ebuild please, including the comments there.
It's also optional, from your output: Optional prerequisite ExtUtils::CBuilder is not installed I'm more interested about version failing to compile; any chance you could sent the relevant output?
The optional dependency on extutils-cbuilder is impossible since it requires module-build to be built (hence why it is a pdepend, not an (r)depend). Closing this out since there was no response to yuval a month ago.
