TeX Live and MacTeX ⇒ dvips not working / pstricks?

[jotacebusta]

Hi all,

I'm having problems with dvips:
Lyx says something like "an error occurried while running dvips -t a4 -o 'Aplicaciones-Integral.ps' when I try to update the pdf. However the dvi file is "correct".
When doing things with Kyle, I can compile and produce the dvi correctly, but when I try to convert to ps I also obtain an error, but only when trying to create a ps file from LaTeX using pstricks. With lyx, the problem arises with every document.

When I try to ruin dvips from a terminal I obtain the following error:
This is dvips(k) 5.96.1 Copyright 2007 Radical Eye Software (http://www.radicaleye.com)
' TeX output 2008.11.01:0841' -> Trabajo1.ps
dvips: ! Couldn't find header file pst-algparser.pro.
Note that an absolute path or a relative path with .. are denied in -R2 mode.

Note, however that the "Trabajo1.tex" file uses pstricks. I don't have any problem when I do not try to use pstricks.

I'm using Ubuntu 8.04 on an intel centrino computer.
Everything started to go wrong when I tried to use pstricks figures produced by GeoGebra in a document that I was writing using LyX.

Regards
