From profiles/base/package.use.mask: # Jauhien Piatlicki <jauhien@gentoo.org> (10 Feb 2015) # Mask until sys-devel/llvm-3.6 is in the tree dev-lang/rust system-llvm But sys-devel/llvm-3.6.0 has now been added to the tree and unmasked. I have not yet checked whether rust actually builds with the flag set, but either the mask should be removed or the message should be updated.
Heather@Cynede.net is listed in metadata.xml, but does not have a bugzilla account. Please remove this.
I have no possibility to check system-llvm just now, but I have asked folks. Thanks for reporting.
Done.
