This is related to #2269 and #2272. The sylpheed ebuild is encoded to require gdk-pixbuf only if gnome is USEd. I presume that gdk-pixbuf would be usable for sylpheed without gnome, but that needs more research.

This continues to be an issue, related to Bug #7693 There is no reason to require Gnome support to be USEd in order to import graphical capabilities in Sylpheed, save for the unfortunate requirement of Gnome in the GDK-Pixbuf library.
Created attachment 7931 [details] Updated ebuild This ebuild is updated to use the new version of Sylpheed (released today, 04 Feb 2003), and includes the updates to include the GDK-Pixbuf library regardless of the state of the USE="gnome" option. This relies on Bug #7693 bring resolved.
