The BSD is one of several Free and Open Source (FOSS) licenses that are 
compatible with GPL. (However, the old version of BSD is not compatible 
with GPL because of the requirement of attribution.)

Follow these links to read more about compatibility and which licenses 
are compatible with GPL:

    * http://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html#WhatIsCompatible
    * http://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html#WhatDoesCompatMean

The list of licenses compatible with GPL v3 has increased tremendous as 
compared with v2. Another good reason to move to GPL v3. Follow this 
link to see all licenses compatible with *GPL v3*:
