icedtea requires pkgconfig during the configure phase to locate and use some dependencies. If pkgconfig is not installed, configure may error out with messages that it could not find the dependencies. Reproducible: Always Steps to Reproduce: 1. emerge -C pkgconfig 2. emerge icedtea Actual Results: ebuild fails, stating that XPROTO could not be found, and suggesting to install the xorg-x11-proto-dev package Expected Results: ebuild should complete successfully Determining that pkgconfig was the missing dependency require digging around in the configure script. The build output could lead one to believe that xproto was missing or not stated as a dep, even if it was. This may have been the case for bug #389599. To workaround, `emerge -1 pkgconfig` before proceeding with the original emerge.
Fixed in icedtea-6.1.10.4-r2 and icedtea-7.2.0-r2. Thanks for the report.
