As a side note, you could replace the second and third spawn commands with
the OS-independent FILE_DELETE and FILE_MOVE commands.

Maybe you can just run a simple test perl program and capture the output
from spawn.
For example,

spawn,'perl -h',tt
if N_elements(tt) GT 1 then begin
;Now do the real perl command
endif else message,'PERL not installed, postscript file not updated'

Another kludge would be write a little IDL program that reads the postscript
file one line at time, tests for the presence of the "IDL graphics" line
and updates it and writes the line to a new postscript file. Or you
could read the entire postscript file into an IDL string array, and then do
a global replace on the offending text.
