x11-plugins/purple-hangouts-0_p20181202.ebuild applies a patch to the package's Makefile (purple-hangouts-0_p20181202-makefile.patch) which enables parallel compilation. As per upstream issue #219 (https://github.com/EionRobb/purple-hangouts/issues/219), this patch creates a potential race condition which can result in a compile failure. I have not been able to reproduce this problem myself, and as such no relevant logs can be provided. Feel free to pursue it with upstream if you have any questions.
