Hello community,
this is my first question - please be kind.
I try to install Win32::ToolHelp with x64 Strawberry Perl on Win7 64.
When I use cpanm I get an dmake error: Build.log:

Please could someone explain the problem for me.
It is the first time I try to install a Win32 Module from CPAN with Strawberry Perl.
Thanks for your help !!
