First, libgnome-vfs2_0-devel provides pkg-config support, but not gnome-config support. Since it seems like most of the panel applets use gnome-config to test for requirements during configure, this is a problem.
I slapped together a /usr/lib/vfsConf.sh that just forwards the pkg-config info, and I'll have a new package (libgnome-vfs2_0-devel-2.2.2-2mdk) ready in an hour or so. You'll need this new package to build some of the panel applets I'm packaging (but not to install binaries). Second, the naming, version numbering, and virtual packages are really inconsistent between the various Gtk+/Gnome packages, which makes it really annoying to port Redhat packages. For example, looking only at the packages that quick-lounge-applet requires: * libgtk+2.0_0-devel provides no virtual names * libglib2.0_0-devel provides glib2-devel, libglib2-devel, libglib2.0-devel * libglade2.0_0-devel provides libglade2.0-devel * libgnome2_0-devel provides libgnome2-devel * libgnome-vfs2_0-devel provides gnome-vfs2-devel, libgnome-vfs2-devel * libgnome-desktop-2_2-devel provides gnome-desktop-devel, libgnome-desktop-2-devel * libpanel-applet-2_0-devel provides libpanel-applet-devel, libpanel-applet-2-devel, gnome-panel-devel So, some of the packages are named libnameMAJOR_MINOR-devel, while some are libname-MAJOR_MINOR-devel. Some provide libnameMAJOR-devel as well, some don't. Some also provide libname-devel, name-devel, and/or nameMAJOR-devel. (There are similar issues with the libnameMAJOR_MINOR non-devel packages, of course.) In other words, I can't count on listing libnameMAJOR-devel as a requirement; instead, I have to do an rpm -q --provides on each one to see what I can list. It would be really nice if someone would go through and fix all of this--get rid of the extra trailing hyphens in some of the packages, provide all four useful virtual packages (plus whatever others are appropriate, like gnome-panel-devel, and whatever's needed for backwards compatibility with the existing packages, like libpanel-applet-2-devel and libpanel-applet-2_0-devel).
