Margaret,
  We're using NetPBM version 9.23, your version may be too old.
  I compiled the version we're using from the source rather than
  using an RPM, but we can determine if this is going to matter for
  you or not by having you test a few things.
  Can you do a quick test for me?

Try this:
  Edit the vmdmovie.tcl script, commenting out, or deleting the
  this line of the code:
    cleanframes ;# delete temporary files and single frames

  Once you've done that, restart VMD (if you still had it running)
  and then run the movie maker as usual. Everything will be the same,
  except that none of the files will be delete when it finishes.
  
  When its done, look at see what files it left in the directory,
  and mail me the list.

  Then, try running ppmtompeg manually by changing to the working
  directory where the animation files were stored, then run ppmtompeg
  with this command:
    ppmtompeg foo.par (where "foo" is the name you chose in the movie gui)

  Send me any errors or interesting looking output from ppmtompeg.

In the case that it looks like NetPBM is bombing on you, I have
copied the Linux binaries that I built, which work fine for us,
into a directory on our FTP server where you (and others) can
download them if you like:
  ftp://ftp.ks.uiuc.edu/pub/mdscope/vmd/netpbm-linux
 
You'll need ppmtompeg, sgitopnm, tgatoppm, and probably a
couple others that might be called by ppmtompeg.

Let me know how it goes and if you still need help getting it running.

Thanks,
  John Stone
