weird C++ errors linking games/bzflag in my environment (NetBSD/amd64 9.99.81)

So I'm getting these weird C++ errors linking games/bzflag in my
environment (NetBSD/amd64 9.99.81).

At first I though the appearance of "-static" was bleeding through from
some of my hacks to static-link more things in pkgsrc, despite the fact
I had explicitly disabled those hacks for games/bzflag.

However I see it is actually in the original source:

$ make extract
$ cd $(make show-var VARNAME=WRKSRC)
$ fgrep static src/bzfs/
bzfs_LDFLAGS = -export-dynamic -static

If I actually remove that "-static" from the original Makefile, then it
links without any errors.

However I also note that there's an official build of the package
available, so it must link OK in a completely stock environment.

I don't know enough about C++ to know what might be the problem in my
environment -- I only find "mangled"(?) symbols that might match the
undefined ones in my /usr/lib/libc++.a (and the same in
