It depends on whether you agree with the FSF that having the "user
perfrom the link" is a violation of the GPL.  The reason is that this
is a subterfuge.  No one person along the way is doing something avoid
the terms of the GPL, but the result is the same.

Clearly, different people have different ideas about the claim that
the FSF makes.  But I agree with the FSF interpretation.  If you
accept the other interpretation, and say that it is OK to have the
user perform the link, then the GPL is weakened to the point where it
might as well not exist.  In any case where the terms of the GPL would
be violated by distributing non-free software linked with GPL
software, we could just distribute the parts separately and ask that
users perform the final step of linking them together.

I thought that the reason that this discussion started was that the
license for some dependency of the GPC package included a clause about
noncommercial use, which conflicts with the GPL.
