'cl' is the compiler executable on windows that was used to compile your perl (do a 'perl -V' and see for yourself). The libwin32 package must have pieces that need compiling. If you don't have Visual C++ around you're outta luck, AFAIK.

Note that you can use PPM to install local files as well. If you download the .ppd file and archive used you can just execute 'ppm install <blah>.ppd' as long as the file the PPD references is in the right relative location.

For instance, the PPD I created for Class::Date (at http://openinteract.sourceforge.net/) looks like this:

<SOFTPKG NAME="Class-Date" VERSION="1,0,6,0">
    <TITLE>Class-Date</TITLE>
    <ABSTRACT></ABSTRACT>
    <AUTHOR>dLux (dlux@kapu.hu)</AUTHOR>
    <IMPLEMENTATION>
        <OS NAME="MSWin32" />
        <ARCHITECTURE NAME="MSWin32-x86-multi-thread" />
        <CODEBASE HREF="./Class-Date.tar.gz" />
    </IMPLEMENTATION>
</SOFTPKG>
[download]

This means that the file Class-Date.tar.gz needs to be in the same directory as the .ppd file. Sometimes they're in a subdirectory, like:

        <CODEBASE HREF="win32-x86/Class-Date.tar.gz" />
[download]

Just make your local directory tree mirror this and you'll be good to go.
