importing postscript and text in Lyx 1.1.5

[Gursoy TURAN]

I am running LyX 1.1.5 on Red Hat 6.2

I am trying to include a figure, which I saved in XFIG as two files: the
postscript, and the text part. According to the manual I only need to
import the text file as (INSERT-INCLUDE FILE with the "use as include
option flag") I got an error.

           can't write on file '/<mydirectory>/analysis.aux
            Please type another output filename

I didn't define an output file, it must have been LyX itself.
The I tried the following according to a footnote in the users manual


I added a line like

         \@namedef{Gin@rule@ps_tex}#1{{eps}{ps_tex}{#1}}

in the file /usr/lib/texmf/tex/latex/graphics/dvips.def. Then added
"pstex" to the extension:

         \def\Gin@extensions{eps, ps, pstex, eps.gz, ps.gz, eps=2EZ}

Unfortuantely it didn't solve my problem either.

Does anybody have an idea how to do this?



Thanks
