Message: warning MSB6002: The command-line for the "DCC" task is too long when installing latest release for BCL

I am assuming that this relates to the message left in the BIZ forum.
Any idea how to make this work?

It's failing with this: The specified task executable "dcc" could not be run. The filename or extension is too long [d:\TMS\Business\packages\d11\tmsbcl.dproj]


Please check your default Delphi library path. Probably it's too big, and it's hitting a limitation in command-line compilation which is limited to 65536 characters (if I'm not wrong).
