I have the same problem. emerge -vpt media-libs/mesa output: These are the packages that would be merged, in reverse order: Calculating dependencies ... done!

What other Mesa drivers support OpenCL? If you're using proprietary drivers, you're not using drivers from Mesa and you should disable opencl for mesa.

Yarda's method of ebuild editing doesn't work for me because the mesa doesn't compile with USE=opencl. Disabling opencl flag helped me. In my opinion it would be nice to change opencl flag description in metadata.xml to "Enable the Clover Gallium OpenCL state tracker for Radeon cards." to not mislead users.

According to https://wiki.gentoo.org/wiki/Intel, Opencl is supported on Intel gen7. Should that separate package (beignet) be built, and mesa left with USE=-opencl?
opencl no longer depends on the llvm radeon backend since 10.2.0_rc4
