I completely misunderstand this email because I 
don't understand how 3-clause bsd is related to 
The FreeType Project license (so I mixed up with 
4-clause bsd license and thought your were 
referring to that paragraph).

The relevant sentence - imo - is:

      If you use
      it, or  only parts of it,  in a program,  you must acknowledge
      somewhere  in  your  documentation  that  you  have  used  the
      FreeType code. (`credits')

I believe it is possible to fulfill this with 
FFmpeg libraries compiled under LGPL and linked 
to a commercial program (and libfreetype) but I 
don't think we can test this in configure.

IANAL, Carl Eugen
