I seem to be unable to install most CPAN modules any more. I'm running Strawberry Perl 5.10.0 for MSWin32-x86-multi-thread. Output from an example follows:

Running install for module 'Parse::RecDescent'

The jobs always fail in the same way:

I dont understand why perl script "w" is being executed? I'm sure the problem is something to do with Test::Pod - but how to fix? I'm having similar problems with almost every new module I try to install.
