It seems keywords were "conveniently" dropped as part of a version bump. Please note that you are required (see devmanual.g.o) to notify the arch teams involved (so that informed decisions can be made as to what course of action to pursue, and so that users can be informed through the recorded decision). Dropped keywords: ~alpha ~ia64 ~mips ~ppc64 ~sparc.
I'll drop mips. No package in the tree with mips keywords needs this. For other arch teams, these are the packages keyworded on your arch that (r)depend on sci-libs/netcdf: alpha: sci-visualization/grace ia64: sci-visualization/grace ppc64: sci-libs/gdal/gdal sci-visualization/grace/grace sparc: sci-visualization/grace
Alpha keywords dropped.
ia64/sparc keywords dropped
ppc64 done
