BLFS 11.3: aMule fails to compile

My BLFS 11.3 is going well. Slowly more packages get added. Four window managers are in and working. Xorg is fine. Audio working as it should. ffmpeg and many codecs are installed. Audacious plays.

I am trying to compile aMule and it's failing. The output of the make:

Anyway, I'm at a loss as to what to do. Has anyone else had this problem and somehow got through it?

Thank you in advance.
