Conventional wisdom: don't force install the version for 5.12 in a 5.10 Perl...or any other version > 5.n into a 5.n Perl.

There are exceptions, but as a general rule, mismatched modules are not likely to be compatible.

Instead, try for the 5.10 version. And per (your line 12), you may still need a good "make"
and, minor afterthought, but your text refers to "file::stat" which ignores the fact that Perl is case sensitive.
