Don't know about your .configure problem, but you can get amule with apt.
If you have a debian style hd-install, start with typing "dselect update" to update your database, then type "apt-cache search amule" to find something installable, "apt-cache show amule" to check the version if you're interested, "apt-get -s -t unstable install amule" to see if it would install ok and leave out the -s for simulation to actually install if the output looked ok.
