i had similar problems with Mandrake 7.2 and some rpm's packages
(gnapster for instance), in all cases downloading sources and building
from scratch fixed all problems.
With mandrake i suggest to install/update it using "developer" version,
then download vdk/vdkbuilder sources tarballs and build them using this
proc:
- unpack vdk
$ tar xvzf vdk-1.2.5
- build
$ cd vdk-1.2.5
$ ./configure --prefix=/usr --enable-gnome=yes
Optionally have libsigc installed and configure adding --enable-sigc
$ make
- install (having su privileges)
# make install

- unpack vdkbuilder
$ tar xvzf vdkbuilder-1.2.5
- build
$ cd vdkbuilder-1.2.5
$ ./configure --prefix=/usr
$ make
- install (having su privileges)
# make install
# ldconfig

vdk/vdkbuilder was tested also in mandrake distributions and show to
work fine.
hope this helps, let us know if problems remain.
