vips has it's own ppm writer, so that's always there at least. You could try:

  vips im_LabQ2ppm somefile.v file.ppm sRGB

to get an sRGB ppm file. Also, vips is probably available packaged for
your linux. Try something like

  apt-get install nip2

Then you can just enter:

  nip2 somefile.v

to view.

There's a page on the vips website about the benchmark, if you're
interested in the background:
