I'm also able to reproduce the failure. The situation, as far as I can 
see,is as follow:

The problem was reported in bug #160637[1]. The maintainer solution[2] 
applied was patch the ebuild to check if epoll support was enabled in 
the kernel.

Ebuild works just fine, detecting if the kernel has the epoll support 
enabled[3] and adding the proper --enable-epoll in that case.

So if the kernel has support for it, the problem should be in a 
different place, probably glibc or linux-headers. I found a test case[4] 
you can run just compiling it.

Later, I'll reopen the bug and see if one of our toolchain ninjas can 
give it a try.

As a workaround, you can disable the epoll support commenting out the 
"myconf ..." line in the ebuild (not tested but should work).

Thanks for reporting,
Regards.
