OK, I found Sys::CPU in backpan. One has to look under the original authors name and THAT is only found by doing a google search... finding the github repo. http://backpan.cpantesters.org/authors/id/M/MZ/MZSANFORD/
I've got the same issue. Searching CPAN shows the module may not exist anymore... At least not under that name. I can't seem to locate it on BACKPAN either
Uh, it compiles, but the oAuth redirect fails with a known 404 error... They're working...
