in thread Problem with PDL module

In that case, complain to whomever provided "install PDL", they messed up

Or, try one of the many instructions from PDL-2.4.11/win32/INSTALL

like

ppm install http://www.sisyphusion.tk/ppm/PDL.ppd or, for the latest PDL developer release: ppm install http://www.sisyphusion.tk/ppm/PDL_dev.ppd
