Can't locate object method "gif" via package "GD::Image"

[wen@japan.email.ne.jp]

Hi,gurus,
When I try to run a perl CGI script I get a error message 
"Can't locate object method "gif" via package "GD::Image" at 
/usr/lib/perl5/GIFgraph/axestype.pm line 119." 
in /var/log/apache/error.log. The line 119 of axestype.pm is
"return $self->{graph}->gif".
Would someone tell me what is wrong?
My Debian version is unstable and the version of libgifgraph-perl
is 1.10-2. 
Thanks in advance.


Regards,
