I was only using the matrix operations defined in pdl up to now but I decided to try to explore its 3d plotting capabilities (instead of using matlab right away). However I am having trouble in installing either the TriD or PGPlot packages. The ppm package for PDL does not include TriD and I have failed in installed PGPlot for sometime, though I have installed its external dependencies (which is extutil-77 as cpan says) I still cant install it due to external dependency problems..
Are there any suggestions you could give to me on this matter? thanks... -- "The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations — then so much the worse for Maxwell's equations. If it is found to be contradicted by observation — well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation." — Sir Arthur Stanley Eddington
