I confirm djview3 and djview4 work fine on the xo (xo 1.5 with sugar
0.84.16) where I had previously installed djvulibre and djview3/djview4.

The sugarise script did produce a working xo package and I was able to
launch the activity + read a djvu document perfectly. 

However, after having copied the xo package on another xo (XO 1.5
running from a SD Card), without previous djvulibre/djview installation,
I ran into unmet dependencies. I had an error while loading djview4 and
libQtGui.so.4.

Copying djview from the build system to the target system (e.g.
in /usr/local/bin ) should solve the problem, however this is not a
solution in order to create a portable activity.

Sorry for the basic issues, I am not a developper.

Regards,

Samy
