GNOME seti applet

I would like to try to get it made for a Fedora core,
beta 3 system. When I run configure it gets to this point:

>checking for gconftool-2... /usr/bin/gconftool-2
>checking for libpanelapplet-2.0 libglade-2.0
libgtop-2.0 >= >2.0.0... Package libgtop-2.0 was not
found in the pkg-config >search path.
>Perhaps you should add the directory containing
>`libgtop-2.0.pc'
>to the PKG_CONFIG_PATH environment variable
>No package 'libgtop-2.0' found

I have libgtop-1.0.12-20 installed. If Fedora Core is
the latest and greatest Redhat, shouldn't it have a
high enough version of it?

Thanks
