Hi Orion, all:  I've just uploaded a new version of PDL-Graphics-PLplot to 
CPAN (v 0.57) which incorporates some fixes recently merged in from the 
the PDL source tree and also includes an improved plplot_library_tests.t.

This test now compiles and runs the C sources
from the plplot examples directory and compares them to the perl 
equivalent output instead of using canned C output for comparison.

This is currently only tested on Linux/Ubuntu!  The compiling of these C 
sources may not work on Windows, for example.

Best Regards,

   Doug Hunt
