It seems that the download URL http://www.gpleda.org/dist/electronics-menu-1.0.tar.gz is down. The page http://www.gpleda.org has under construction icon, without further details. Do you have another copy of the file? AS this is dependency of other packages it is important to resolve ASAP.
You probably have a bad mirror configured in GENTOO_MIRRORS (make.conf). Please fix that.
Yes, indeed I had a bad mirror. Thanks for pointing it out. Still, the homepage link is broken, but it is not a showstopper.
