    As Slaven says, you're producing uncompressed GIFs.

    You need to install giflib instead of libungif.

    If your OS (or distribution) doesn't provide a giflib package then you
    can get source from:


    Debian provides a giflib3 package, which works for most purposes (you
    can't write/read to/from scalars or via callbacks.)
