x11-misc/gkrellweather-0.2.7-r1 does not require x11-misc/bbweather although it seems to need this before it will work
Created attachment 1221 [details] ebuild with dependency added
nope, it works fine without it. I have gkrellweather running on here for months without bbweather
There IS some missing dependency. gkrellweather requires a programme called GrabWeather which is not provided by gkrellweather. It is provided by bbweather, but maybe something else as well.
GrabWeather is installed, it's just in the wrong place. Take a look at the CONTENTS file for the package. I'll try to fix it later today.
