Perl 5.26.0 introduces an important backwards incompatible change: the current working directory is no longer part of `@INC` by default. http://blogs.perl.org/users/sawyer_x/2017/05/perl-5260-is-now-available.html This makes invocations like this fail: perl -e "use VCSUtils; ..." In order to work with new versions of Perl, the current working directory must be added to the include path before running the `use` instruction, e.g: perl -e "use lib '.'; use VCSUtils; ..." setupgitclone.py has two of these invocations.
