I just checked, and the standard pdl examples work for me on Debian stable
(except I cannot do the map example since plmap is not implemented for that
old version of pdl).  Thus, I suspect there is something wrong/inconsistent
with the version of PLplot that is linked to your version of pdl.

To be sure you are using a modern good version of PLplot with the PDL
available on your platform, here is what I would like you to do (which
follows what I did for the above test).

(1) Build PLplot from the current CVS version (which is quite stable).
Follow the directions at http://www.miscdebris.net/plplot_wiki/ except that
you should use the -DENABLE_pdl=3DON -DBUILD_TEST=3DON options for cmake.
(The first allows pdl and the second allows ctest).  You can stop after
the make command (i.e., at this point you don't have to do the make install
command).  It is a good idea to save all output from the cmake and make
commands in case there is any trouble with the ctest step below.

(2) After executing the "make" command run

ctest --verbose --tests-regex perl >& ctest.out

(drop the --tests-regex perl option if you want to test everything).

You should see postscript files that have been generated in the build tree
test subdirectory as a result of that ctest command.  Use a postscript
viewer to look at them, (e.g., "gv test/x16pdl.ps").  Hopefully you will ge=
t
good-looking results that verify that all is well with PDL and the CVS
version of PLplot on your platform, and we can take it from there to get
equivalent good-looking results for your own pdl examples.

If you notice cmake, make, or ctest errors or get no pdl results, then plea=
se
post to the list with the complete output from cmake, make, and ctest (i.e.=
,
cmake.out, make.out, and ctest.out) attached. Those files are usually neede=
d
to help us figure out what the problem is on any particular platform.
