La respuesta corta es no.

La respuesta mas elaborada es: si un programa tiene licencia gpl entonces los 
derivados tienen que tener licencia gpl.

La licencia bsd no es asi. La licencia bsd no contempla casi ningun tipo de 
limitacion.

De la wikipedia:
"Many users and developers of BSD-based operating systems have a different 
position on licensing. The main difference is the belief that the copyleft 
licences, particularly the GNU General Public License (GPL), are too 
complicated and have restrictions which are undesirable. The GPL requires any 
derivative work that is release to be released according to the GPL while the 
BSD licence does not. Essentially, the BSD licence's only requirement is to 
acknowledge the original authors, and poses no restrictions on how the source 
code may be used. As a result, BSD code can find its way into proprietary 
software that only acknowledge the authors. For instance, the IP stack in 
Microsoft Windows and Mac OS X are derived from BSD-licensed software."
