The stackexchange page has pdftk as its first choice

However, my machine which has the postscript files is offline (no internet
connection) and no pdftk is available to do this :(

The psmerge utility part of psutils is available but does not work.  It is
referenced here

Thanks for your input.  I may have to copy the files and take them to
another machine so I can try to use pdftk or maybe use a command from
imagemagick which can do the job?

Best Regards,
