The reason for this is there is no version number on the library name  
that Genser builds.  Where it used to be libherwig6510.dylib (for  
example), it is now just libherwig.dylib.  Do we have any plans for  
distinguishing between generator versions?  Even worse, like every  
other OS X user I never enabled the case sensitive file system (some  
legacy Adobe apps break when you do that apparently) and so the Herwig+ 
+ library name actually matches the fortran Herwig library!
