[OS X TeX] pstricks question

[Sergei Mariev]

I use tex and ghostscript to typset this file. Here is another 
strange thing: If I use \psset{nodesep=2pt,levelsep=5ex} instead of 
the optional parameter _in preamble_ it typsets everything just the 
way I want it. If I use this command in the body of the document, it 
issues the same warning. Do you mean that even if I use tex and 
ghostscript instead of pdflatex, I  would not make it work? Why does 
it work if I include this line in the preamble?
