Re: Changing @INC path detail

use lib is the Right way to do it, but you can also do it the same way you manipulate any other array:

my $override_lib_path = "/usr/local/Perl/5.8.6/whatever";
my $backup_lib_path = "/lastresort/path/to/lib";

# look in $override_lib_path first
unshift @INC, $override_lib_path;

# look in $backup_lib_path last if
#  no match for a module name is found first
push @INC, $backup_lib_path;

Good luck.

You have to take care that you fold that into a `BEGIN` block, because use is evaluated at compile time. If you have a script like this: `# modify @INC use Some::Module;` [download] the `use` is evaluated before the `# modify @ING` line. You see, it's not as easy at it looks, which is why `use lib $path;` is recommended. (It checks for duplicate entries in `@INC` as well, which is another advantage).	[reply] [d/l] [select]

BEGIN

use

If you have a script like this:

use

# modify @ING
