make install problem on Gentoo

[Mike Blackwell <mkblackwell@xxxxxxxxx>]

I'm having an issue building the latest master branch on Gentoo linux. Configure and make succeed as expected, but "sudo make install" fails on PMDA, and I'm having trouble unwinding the nested make-ing that's going on to figure out the problem... Here's the output:

There's a blog post from back in 2011 that maybe hints at the problem but doesn't fully explain the solution for PMDA (and I'm not trying to make an ebuild): http://blahg.josefsipek.net/?p=440.

Any insight appreciated!
