If you you want to see graphical bug charts (plotting historical data over
time), you should install libgd and the following Perl modules:

GD: /usr/bin/perl -MCPAN -e 'install "GD"'
Chart: /usr/bin/perl -MCPAN -e 'install "Chart::Base"'

If you want to convertBMP image attachments to PNG to conserve
disk space, you will need to install the ImageMagick application
Available from http://www.imagemagick.org, and the Image::Magick
Perl module by running (as root):

/usr/bin/perl -MCPAN -e 'install "Image::Magick"'

If you you want to see graphical bug reports (bar, pie and line charts of
current data), you should install libgd and the following Perl modules:

GD: /usr/bin/perl -MCPAN -e 'install "GD"'
GD::Graph: /usr/bin/perl -MCPAN -e 'install "GD::Graph"'
GD::Text::Align: /usr/bin/perl -MCPAN -e 'install "GD::Text::Align"'
Template::Plugin::GD: /usr/bin/perl -MCPAN -e 'install "Template::Plugin::GD"'

If you want additional HTML tags within product and group descriptions,
you should install:
HTML::Parser: /usr/bin/perl -MCPAN -e 'install "HTML::Parser"'

Bugzilla requiressome Perl modules which are either missing from
your system, or the version on your system is too old.
They can be installed by running (as root)the following:
/usr/bin/perl -MCPAN -e 'install "MIME::Parser"'
Minimum version required: 5.406
/usr/bin/perl -MCPAN -e 'install "Mail::Mailer"'
