question on @INC

i recently tried to run a module PGPLOT.pm within the PDL package.
at the PDL command line i typed "use  PGPLOT"
i get the following error message:
Can't locate PGPLOT.pm in @INC (@INC contains:
/System/Library/Perl/5.8.6/darwin-thread-multi-2level
/System/Library/Perl/5.8.6 /Library/Perl/5.8.6/darwin-thread-multi-2level
/Library/Perl/5.8.6 /Library/Perl
/Network/Library/Perl/5.8.6/darwin-thread-multi-2level
/Network/Library/Perl/5.8.6 /Network/Library/Perl
/System/Library/Perl/Extras/5.8.6/darwin-thread-multi-2level
/System/Library/Perl/Extras/5.8.6 /Library/Perl/5.8.1 .) at (eval 44) line
4, <STDIN> line 1.
BEGIN failed--compilation aborted at (eval 44) line 4, <STDIN> line 1.

however when there is a PGPLOT.pm module in
/Library/Perl/5.8.6/darwin-thread-multi-2level/PDL/Graphics/ and also in
/Users/anjan/.cpan/build/PDL-2.4.3/Graphics/PGPLOT/

Does this mean that I will have to add extra paths to the @INC variable?

Appreciate your help,
Anjan

How did you install the module?
Try adding this line before the use PGPLOT:
use lib '/Library/Perl/5.8.6/darwin-thread-multi-2level/PDL/Graphics/';
