gtk2-dev.tcz lists Xorg-7.6-dev.tcz as a dependency
meanwhile I continue to have glib2 issues building leafpad. No issues with libpng anymore thanks. Also No errors during build but three warnings of depreciated symbols still plagued with this terminal error when attempting to start the application.
symbol lookup error: /usr/local/lib/libgobject-2.0.so.0: undefined symbol: g_datalist_id_replace_data
there is only one copy of libgobject-2.0.so.0 installed, but I think it's an issue with the entry in gobject.c, could always be a missing dep ?
Meanwhile am thinking about rebuilding this system with a clean optional dir, you know start over with fresh downloaded deps..
Edit: ok it turns out to have been one old dep too many, when booting to a test (minimal onboot list) config the updated leafpad works fine, so I guess i should have cleaned out the optional dir earlier
