Are these licenses DFSG?

[Eugen Dedu <Eugen.Dedu@pu-pm.univ-fcomte.fr>]

Hi,

We have a bug report,
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=532456, about licenses
of various plugins of opal package, and I do not know if the licenses
involved are DFSG-free.  Could you please tell me if these plugins are
allowed to be in debian main?

Thank you,
