I provide the newer version of wv2 for Lenny in the dependencies PPA. There were significant differences between the two APIs that forced the following changes in SVN: r1082110 r1082138 r1082651
Woohoo! I modified the build script so that if wv2-0.2.3 is detected, to reverse the three patches. Koffice compiled.
Took 109 minutes!
Next step is to install wv2 0.4.2 and then try to build again.
