[Pdx-pm] CPAN.pm and prerequisite_policy

[Chris Dawson]

I have been searching in vain on google for the answer, but I cannot 
figure out programmatically how to modify the Config hash in CPAN.pm.  
Is this not correct?

use CPAN;
$CPAN::Config->{ 'prerequisites_policy' } = 'follow';
install( "XML::LibXML" );

I want to temporarily ask CPAN to follow all dependencies. 

Thanks,
Chris
