This looks similar to Yocto Bug 1233 
(http://bugzilla.yoctoproject.org/show_bug.cgi?id=1233

Can you confirm if you have the following commit in your branch?
http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=2429773613cb95b6a0541b5cce6ce1338d5cfc2b

It's possible you might be missing this and it's not finding the file 
correctly.

As Richard mentioned also, an strace output would be helpful if you do 
have the above commit.

Thanks
	Sau!
