'overriding' is misspelled as 'overridding' in the Portage Eclass Warning when using overlays. "It is best to avoid overridding eclasses from PORTDIR because it will trigger invalidation..." Reproducible: Always Steps to Reproduce: 1. Install layman and add an overlay (i use mozilla and ruby) 2. Add 'source /etc/portage/local/layman/make.conf' to /etc/make.conf as instructed 3. Run emerge command (i.e. emerge -va ruby)
Thanks, this is fixed in 2.2_rc9.
