This is right, but GPL is incompatible with the BSD license.

You are not allowed to remove the BSD license and to replace it with the GPL.

1)	You are not allowed to remove the BSD copyright notice

2)	BSD forces you to tell your users that you did incorporate code
	from a specific Author (the one who wrote the BSD'd code).

3)	I doubt that the original Author would like to see his
	code published under a less free (in this case the GPL) license 
	than he originally used.

However, there is no problem to use *BSD licensed code from a GPLd project.
