I had to get rid of the \rnode and \ncline calls - apparently I don't
have the packages where they are defined.
But once I did that, the preview succeeded and I get a box around
"text in box".
Org-mode version 8.3beta (release_8.3beta-177-gfe133a @
/home/nick/elisp/org-mode/lisp/)

Are there orgtex*.tex files in /tmp? If so, try processing one of those
from the command line and see what you get. If not, the trick I use is
to introduce a deliberate error (call undefined macro \foo) in the tex
code and then try the preview. That leaves a .tex file behind, which I
can edit to get rid of the error and then process by hand. It might be
interesting to compare that with what you have above.

I don't know whether this causes your problems (probably not),
but as the doc for the variable says, it's not a good idea to change
org-latex-default-packages-alist unless there is a conflict. You should
add the pstricks entry to org-latex-packages-alist instead and leave
org-latex-default-packages-alist alone.
