Dwimperl was a Perl distribution that included a lot of pre-compile CPAN modules. As the project has not been maintained for a long period of time its website was disabled.

Instead of that I suggest:

MS Windows

Strawberry Perl

Linux

The Perl that comes with the Operating System.

DWIM Perl

If you'd really like to find DWIM Perl you can do so on GitHub:

You can find the source of the website and in general the sources of the project on GitHub.

Feel free to reuse them as you find that fit.
