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

As I think I mentioned before the build failure is most likely due to the
missing .la file from the newer version of wv2.  If you really want to use
the older version, you will need to reverse the previous three patches
(which could be done automatically) before koffice will build.  What I
would do is copy the koffice source, reverse patch the copy, then run a
diff between the original and the copy.  You can then automatically apply
that single diff file to the source prior to build as part of your build
script.  Other distros have had to do similar hacks over time as the
official KDE sources migrated to new versions of system libraries; this
situation is quite similar.

Hope this helps!
