CentOS 5 :: Perl CPAN GD Module Failing - Can't Locate Object Method "png" Via Package "GD::Image"

I have CentOS 5.4 and have installed CPAN GD module.Installation messages seemed clean and successful.When I try to create a png file, perl gives the error message :

Can't locate object method "png" via package "GD::Image" at
/usr/lib/perl5/vendor_perl/5.8.8/DBD/Chart/Plot.pm line 1276 (#1)
(F) You called a method correctly, and it correctly indicated a package
functioning as a class, but that package doesn't define that particular
method, nor does any of its base classes. See perlobj.

Also, the following perl one-liner gives answer "No".

perl -e 'use GD; $im=GD::Image->new(); print $im->can("png") ? "Yes" : "No" , "
";'

I suspect that this GD module requires Image::Magick, but that borks on installation.
