I don't believe the situation is that simple.
Currently, libogc is under the zlib license. Which is GPL compatible, but not Copyleft. The inclusion of GPL code means libogc must be distributed under terms of the GPL, which puts more limits on the code than the some contributors may be comfortable with.
As there is no CLA, and zlib has no sublicense clause, the copyright holder (contributors) should be consulted if the project is going to become governed by a restrictive license.
