Nigel,

It's definitely not a ubuntu thing.

Here is the script that worked on my Debian system, which means it will work on a Ubuntu
system as well:

###################################################3
 #!/bin/sh
 infile=$1
 outfile=$2

 pdftops -level3 -paper match "$infile" - | gs -q -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dPDFSET + TINGS=/ebook -dAutoRotatePages=/None -dEmbedAllFonts=true -dSubsetFonts=true -sOutputFile="$outfile + " -dCompatibilityLevel=1.4 -c .setpdfwrite -
###################################################3

I saved the above as a pdfcompress file and changed its permissions to
executable by "chmod 700 pdfcompress". Then, I downloaded a random pdf file
http://www.google.com/url?sa=t&ct=res&cd=4&url=http%3A%2F%2Fwww.irs.gov%2Fpub%2Firs-pdf%2Ffw4.pdf&ei=urSISOO5NZmIiwHFjsHhDA&usg=AFQjCNHdJoiSxm8m_ff8SZ6jMDWjFVFBMQ&sig2=aCsIh59K1wBclOnIfl507w
and ran "pdfcompress fw4.pdf fw4compressed.pdf" and obtained the desired
compression result:

-rw-r--r-- 1 malex malex  41106 2008-07-24 11:03 fw4compressed.pdf
-rw-r--r-- 1 malex malex 242545 2008-07-24 10:58 fw4.pdf

Cheers,

Alex.

P.S.: And by the way, Debian and Ubuntu Ghostscript package names have changed
around May 2007. All those gs-afpl gs-gpl gs-esp packages have been unified
into a single "ghostscript" package with a "gs" binary executable.
