When the userpriv FEATURE is enabled, portage falls to call ccache during the compile. Reproducible: Always Steps to Reproduce: 1.Install and configure ccache with userpriv FEATURE enabled. 2.Emerge some package several times 3.Look at the results of ccache -s Actual Results: The ccache is less than one megabyte and there are no ccache hits. Expected Results: The ccache should have expanded in size.

Did you use the right CCACHE_DIR (should be /var/tmp/ccache) when you checked for ccache activity?
This seems like possibly a duplicate of bug 162542. Please try with portage-2.1.5.4.
Closing as need info. Feel free to reopen if you're able to reproduce it with a recent portage version.
