in thread perl code for linear regression

Port? Is there any reason to believe it won't work on all systems? And if it doesn't, how is copying the source going to help?

Maybe you meant to ask if you can install this particular module by copying the source because you have some problem using the directed installation procedure. It looks like you could since it's pure Perl, but there's a big "Module/Install/" directory in the distribution, and I don't know what it does.
