It may not be distributable at all. If it is distributable, let's
look at the differences between the GPL interactive-use clause, the
old-BSD advertising clause, and this.
First off, unlike the GPL clause, this applies even when the
derivative work is not interactive in any way -- say, part of a
library in an embedded system. It applies anywhere there's an "About"
box. That may or may not be OK. But it also differs critically from
the old BSD advertising clause in requiring prominent display. That's
Perhaps you can contact the copyright holder, point out the
interactive-use clause of the GPL, and ask that he rely solely on that
instead of on an extra restriction? Also, it would be wise to check
on whether actually-GPLd code is being used. Good luck.
