[Purdue-pm] . being removed from @INC

[Mark Senn]

The next version of Perl (5.26) may not have . in the include path
for modules, etc.  From
http://blogs.perl.org/users/todd_rinaldo/2017/05/reviewing-perl-5-in-inc-at-the-perl-toolchain-summit.html

    As of 5.26.0, Perl will be compiled without . in @INC by
    default. There is a Configure option (-Udefault_inc_excludes_dot) to
    revert Perl to its 5.24 behavior but this is not recommended.

See the web page for more details.
