If the module still exists in the cpan install link, then you can try this.
1. Enter cpan shell by typing cpan
2. In the cpan sheel type,
cpan> install path/to/file//xyz.tar.gz
where path/to/file is the path to the tar file and xyz.tar.gz is the actual tar file.
For example to install an old version of mod_perl module you should give this command:
cpan> install D/DO/DOUGM/mod_perl-0.99.tar.gz
