Hello again, 
      Thanks to Mats and Metod for pointing out ps2pdf and several
others who replied about contacting the author/maintainer of gv. 
       THERE SEEMS TO BE A PROBLEM WITH dvips!
             I have tried doing the following experiment three times
with identical & very peculiar results:

$mkdir test
$cd test
Now create a file hello.tex which is:
*******************************************************
Hello, world!
\bye
*******************************************************
Now I do:
$ tex hello
  This yields hello.dvi. Then
$ dvips hello.dvi -o hello_dvips.ps
  This creates hello_dvips.ps
$ gv hello_dvips.ps

gv open up with the pp p ps file visible (barely to my
cataract-afflicted eyes) but the frame says "gv: hello.dvi"!
Now I do:
$ps2pdf hello_dvips.ps hello_dvips.pdf
When I view the resulting pdf file with xpdf it shows garbage! When I
close xpdf, on the xemacs shell I see 
"xpdf Error:     File contains Type 3 fonts"

Now I do
$pdftex hello 
        This gives hello.pdf
$pdftops hello.pdf 
         This yields hello.ps
$gv hello.ps opens up gv with hello.ps and this time the frame says
hello.ps

$ps2pdf hello.ps  then produces a file hello.pdf which is fine.

        What on earth is the matter?
Help, suggestions will be appreciated.
Kalyan
