dev-libs/Ice/Ice-3.6.4-r1 is latest stable but only supports python3_6, which isn't a default implementation for a while now. Both greater versions (3.6.5 and 3.6.5-r1) supports newer Python implementations. Please stabilize a newer version. https://qa-reports.gentoo.org/output/gpyutils/36-to-37-stablereq.txt
