It depends on which BSD license it is. There are at least two major
versions of the BSD license, and they're usually referred to by the
number of clauses they contain. The newer BSD license has 3 clauses:
1. Redistributions of source code must retain the above copyright
notice, this list of conditions and the following disclaimer.
2. Redistributions in binary form must reproduce the above copyright
notice, this list of conditions and the following disclaimer in the
documentation and/or other materials provided with the distribution.
3. Neither the name of the University nor the names of its contributors
may be used to endorse or promote products derived from this software
without specific prior written permission.
This license is said to be compatible with the GPL because it does not
pose any additional restrictions on the distribution of the software
beyond those already present in (or permitted under) the GPL.
The older BSD license had 4 clauses. The fourth clause, and its
retraction, can be found here:
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change
This fourth clause was *not* compatible with the GPL, because it
placed an additional restriction on the terms under which the software
could be distributed; this made it a violation of licensing to
distribute a software covered by both the GPL and the 4-clause BSD
licenses.
