problem with @INC

Hi,
a use PGPLOT command in the PDL turns up this error:
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 PGPLOT.pm  seems to be present in
1. /Users/anjan/.cpan/build/PDL-2.4.3/Graphics/PGPLOT/PGPLOT.pm
and
2. /Library/Perl/5.8.6/darwin-thread-multi-2level/PDL/Graphics/PGPLOT.pm

any idea how to set @INC so that the PGPLOT modules are correctly located.

i use mac osX 10.4.11

thanks in advance.
