Subject: | Clarify @INC handling in odd situations |
The way @INC and $ENV{PERL5LIB} are treated in ./Build and elsewhere
(such as _perl_is_same()) leads to confusion in some situations.
The current behavior is too complicated, but perhaps cannot be changed
without breaking compatibility.
A workaround is for the user to set $ENV{PERL5OPT} with "-I$dir".
See ticket #29899.
