Yes just like I said, you need a package like libdjvulibre-dev installed,
which contains the development headers.

It is of couse not optimal.

When I added DjVu support (May 2005) this API was basically none existing.
The situation has improved a little bit since than, but still today the
external API doesn't support all the features Ligature supports for DjVu
files.

There is a reason why all of the Windows based DjVu-Viewers, and also
most of the tools included in Djvulibre including the official DjVu-Viewer
(djview), do not use the external API.
