It is not a question of packages not being loaded; otherwise, the 
command \pstree wouldn't be recognized. Instead, PSTricks is not parsing 
the argument. It should separate `nodesep' as the graphics parameter, 
rather than `nodesep=2pt'. Are you using some strange encoding such that 
your = sign is not an ascii = sign?
