Right. SetCwd() will only make a difference to how Perforce computes relative 
paths. For example:

    $p4->Run( "sync", "../../makedist/..." );

The client spec is the ultimate arbiter of what goes where.

Not unless you're intending to work with different files. The normal usage 
would be to have your client spec map ALL of the files your build system 
would work with and then either 'p4 sync' or 'p4 sync-f' to have Perforce 
populate the build tree. Then you build as normal.
