We already have a section in the Known_problems
about 16bit data and rpic/wpic.  Since we have no
other reports from any linux systems for this problem,
my guess is that it may come from a build/config
problem for NetPBM in gentoo.

Maybe Ingo could update the gentoo bug ticket
with the facts we've discovered.  I think the debugging
will involve creating known good 16bit intput and
output files and then tracking down the differences.

For the PDL-2.4.10 release, I think we could just
add a button on our Get PDL section of the web
site for gentoo and put the OS specific note there.
