$subj, as htdigest builds against it
app-admin/apache-tools does not need sys-libs/db dependency. $ scanelf -qF '%F: %n' /usr/sbin/htdigest /usr/sbin/htdigest: libaprutil-1.so.0,libapr-1.so.0,libpthread.so.0,libc.so.6 $ You probably have dev-libs/apr-util built with USE="berkdb" and you probably forgot to use -Wl,--as-needed.
Looks like it, interesting feature though ;)
