Unfortunately I didn't keep the build.log on this machine but I was stuck on this for a week before figuring out this might be something like bug #604802. Looks like another gperf breakage. $ emerge --info app-emulation/libguestfs Portage 2.3.5 (python 3.4.6-final-0, hardened/linux/amd64, gcc-5.4.0, glibc-2.23-r3, 4.10.13-gentoo x86_64)

I can't find the duplicate bug right now, but this is long fixed upstream. Please see these upstream commits: 004de6cf45cfe66ca166cbdcb1c3125a2a81eb31 48d4117789e92489b9a3c6f3456b0770b3fdb290
I've added an ebuild for libguestfs-1.36.5 to bug#601162 that I think would fix this problem, please give it a try.
Just bump to 1.36. Build fine with this version of gperf.
