[Just to make sure I got something to track it down with] The ruby-gdchart package currently has quite a few issues, among which: - dodoc failing in the ebuild; - builds non-PIC code (TEXTRELs); - bundles an internal copy of an ancient library (gdchart) we don't have in portage. Since the package is a leaf (nothing depends on it), it has been decided to just kill it off.
Removed. See ya! :P
