Version missmatch between dev-cpp/ethash and net-p2p/ethminer + net-p2p/ethminer-9999 broken

[V10lator]

First I tried the ~amd64 versions but there seems to be a missmatch between dev-cpp/ethash-0_p20180504 and net-p2p/ethminer-r-0.15.0_pre8:

/var/tmp/portage/net-p2p/ethminer-0.15.0_pre8/work/ethminer-0.15.0_pre8/libethcore/EthashAux.cpp: In static member function ‘static dev::eth::Result dev::eth::EthashAux::eval(int, const h256&, uint64_t)’:
/var/tmp/portage/net-p2p/ethminer-0.15.0_pre8/work/ethminer-0.15.0_pre8/libethcore/EthashAux.cpp:28:36: error: ‘hash’ is not a member of ‘ethash::managed’
     auto result = ethash::managed::hash(epoch, headerHash, _nonce);

So I tried to compile net-p2p/ethminer-9999 but that gives me:

-- Looking for CL_VERSION_2_0
-- Looking for CL_VERSION_2_0 - not found
-- Looking for CL_VERSION_1_2
-- Looking for CL_VERSION_1_2 - found
-- Found OpenCL: /usr/lib/libOpenCL.so (found version "1.2") 
CMake Error at ethminer/CMakeLists.txt:13 (hunter_add_package):
  Unknown CMake command "hunter_add_package".

Should I open a seperate bug report for the 9999 issue or is it ok to keep them together?
