from $prefix/lib/*.

This is where the "perlinc" option comes in.

If "perlinc" is set, it is understood to be a list of paths
(separated by /[ ,;]+/) to be prepended to the @INC variable.

If "perlinc" is not set,
"$prefix/lib/perl5/$perlversion" and
"$prefix/lib/perl5/site_perl/$perlversion" are automatically
prepended to the @INC variable as a best guess.

=head2 Special Option debug_options

If the "debug_options" variable is set (often on the command
line), the list of option files that was searched is printed
out, the resulting list of variable values is printed out,
and the resulting list of include directories (@INC) is printed
out.
