Hello Guix, On my system, perl-sys-cpu's tests fail because of differences in the information available in /proc/cpuinfo. Debian's patch for this perl module seemed nice: rather than trying to fix the related functions, just concede that the module is mostly used just to read the number of available processors and mark the other tests as "TODO". This patch replaces the test file with debian's using an origin snippet. Eric Bavier, Scientific Libraries, Cray Inc.
