kde-base/nsplugins-3.5.9 fails to emerge, looking for glib.h which is missing, should probably make nsplugin depend on the glib package. Reproducible: Always Steps to Reproduce: emerge kdebase-meta without installing glib before hand.
This has been fixed in nsplugins-3.5.10. We should be asking for 3.5.10 to be marked stable soon, so I'm going to close this as later.
reopening to close FIXED, as 3.5.10 is stable
