emerge (configure phase) fails with checking for cpio... no configure: error: cpio program not found in PATH and checking for XPROTO... no configure: error: Could not find Xproto headers - Try installing xorg-x11-proto-devel.
icedtea-6.1.10.4-r1 has xproto dep, are you sure this is not about icedtea-7.2.0-r1 ?
(In reply to comment #1) > icedtea-6.1.10.4-r1 has xproto dep, are you sure this is not about > icedtea-7.2.0-r1 ? I'm absolutely sure. I was tring to update from icedtea-6.1.10.4 when I got xproto error on two different amd64 boxes. But I can't repeat it now. So may be it was some temporical snark. There's also a question where had it (xproto) gone, cause half of my system depends on it... So let's think that it was some trouble on my system. Now it's ok.
The missing deps should now be added.
