Reading through the list of available binary ports of Perl for the Windows platform listed at CPAN here, I found the following packages which may suit:

• http://people.netscape.com/richm/nsPerl/ - pre-built binaries of 5.005_03, 5.004_05 and 5.004_04
• ftp://ftp.activestate.com/ActivePerl/Windows/5.005/Intel/ - the Activestate FTP server with a whole directory of different 5.005 builds, the last looking to be build 522

 

perl -e 's&&rob@cowsnet.com.au&&&split/[@.]/&&s&.com.&_&&&print'
