paludis build-log of build failure

My (source-based) Linux-distribution (Exherbo) recently updated the webkit-package to 2.20.0, which kept consistently breaking in the exact same spot build attempt after build attempt.

The only way i was able to get the build to succeed was by increasing the number of concurrent build-processes from 1 to 2, which gives me the impression somewhere in the build infrastructure exists a dependency that is not explicitly codified. From what i have been able to deduce so far is that the problem lies somewhere in the generation of the "DerivedSources".

I've attached the build-log of one of the failed build attempts.

Hopefully somebody a tad more knowledgeable will be able to figure this one out.
