Mac OS X: the name of the startup script itself must match the
   name of the subdirectory it's located in. Changed MySQL->MySQLCOM 
   in the Do-pkg script and renamed the file in BK. (Thanks to Bryan
   McCormack for reporting this)


Build-tools/Do-pkg:
   - renamed script from MySQL to MySQLCOM to match the name of the
     directory it's installed in
support-files/MacOSX/MySQLCOM:
   - Fixed the file and directory name to match the actual location
