/usr/local/bin/aterm: Permission denied"

Does /usr/local/bin/aterm have a executable bit set? You might want to chmod a+x that binary. Also if all fails, you might want to check if it needs to run SUID.

Shared object "libXext.so.6" not found"

blackbox may be looking at it in a different location. Do

find / -name libXext.so.6 -print

and see where it is (if it doesn't find it, search for just libXext). Once you find it, create a symbolic link to the file, for wherever blackbox is looking for it. Did you compile blackbox from pkgsrc?

Also, is there away to start X right when you load BSD?

There are two possibilities; one, put 'startx' into your shell's rc file (i.e. ~/.bashrc). This will execute anything within the file as soon as you login. Secondly, if you don't want a command line login, you can always use xdm...but be careful not to screw up the config, or otherwise you'll never be able to login. XDM pretty much creates a graphical login screen (like the fancy stuff you see in most Linux distros) and starts an X session for the user.

How did you install it? It's always better to install stuff like this using pkgsrc.

That's a really bad way of doing things. You should never put downloaded stuff into /usr. Create a directory like /stuff instead and put it in there. When you do configure, make and make install it will automatically put things where thet need to be. Also if you don't have a network connection it would make sense to install packages using the precompiled binaries. Download the 2.0 precompiled packages ISO:

ftp://ftp.netbsd.org/pub/NetBSD/iso/2.0/i386pkg.iso

burn it to a CD, and use the pkg_add command to add packages. That way you don't have to compile anything.
