- fix some gdb conflicts
- update the libiodbc portfile to be more like the one in trunk
- gdal: more dependencies
- gis-bundle: more dependencies (will probably need even more)
- weechat: Add Tcl variant, tweak other variants
- cec: whitespace and other minor tweaks

- test patoline some more
- move aside relax3d portfile now that it is in trunk
- work on scilab a little more

mine doesn't.

stuff, too)
