I was not completely clear, I'm afraid.  Gnash was built with gcc under
all circumstances.  libvgl.so is part of the world build and is
installed in /usr/lib.  It was originally built with clang when I built
both the kernel and the world with clang last week.  I found that
building /usr/src/lib/libvgl with gcc was necessary to get gnash to
build properly.
