A viable approach is to disable multimedia, although then you *do* get lots of
dialog boxes. I have not fixed that one yet. support, libs, pimlibs all build
out-of-the-box on FreeBSD-6. I've just discovered that FBSD-6 doesn't have
the _SC_PHYS_PAGES sysconf constant (which FBSD-7 does, and which FBSD-7
documents as a "Solaris and Linux extension").
Here's a patch to do the same with sysctl() on 6-STABLE.
