Hm. Isn't libbfd-2.21.53-system.20110810.so a strange name for a lib supplied with a distro?
Anyway, you installed something from a package and it isn't working. Some required lib is failing or missing.
You can
- spend 117 back and forth posts analyzing that issue with someone who loves to analyze distro problems (like Vollstrecker)
- ask the distro guys (won't help, because it's working in general, just not for you)
- hope for someone posting here "easy, just ..."
- reinstall Ubuntu
- build aMule from source
I suggest the latter (unless you don't mind reinstalling your OS). 12.04 even ships the right wxWidgets version, so it's piece of cake. See
