The first errors are perl warnings. You can ignore them.
the simulator runs from a base directory similar to EQEMu, (or preferably same directory). The error you get is the same error as EQEMu error when it can't find the plugin.pl file
You need to have this file (it can be empty) in the directory you use the simulator from, just like db.ini, the plugin directory (possibly empty), a quests directory , ... i think that's all
