I am trying to run a 3rd-party closed-source app on NetBSD 2.0.2.  It
is linked with libstdc++.so.4, which is not present on my system.  Is
there a compatibility package somewhere that I can install?

I'm a complete newbie to NetBSD, by the way.  I've been using Linux
for many years, but I don't yet know much about NetBSD's packaging
system.

Thanks for your help,
