In your /etc/make.conf file do you have the following line?

EMERGE_DEFAULT_OPTS="--with-bdeps y"

You can do this on the emerge command line if you choose. See man
emerge for info on doing that.

I *think* the standard answer about why this happens is that
--depclean and a basic emerge don't search all the dependencies
exactly the same. If you add the --with-bdeps y option then they do.

Anyway, I don't seem to run into this much using this in make.conf.

Hope this helps,
Mark
