Libraries in the GNOME Platform release are meant to maintain ABI
(binary) compatibility between all releases in the GNOME 2 series.
Libraries in the Desktop release do not have such a requirement. This
has not always worked perfectly, but we have come very, very close to
sticking to this principle. You can see which modules are "platform" and
which are "desktop" here:

Your original post did not really nail down what your problem was,
though. Was the rpm not installing because rpm wanted the
requirement to be satisfied, or were there runtime linking problems?

If it is a linking problem, the you probably need to ensure the linc
package is installed for Mandrake just in order to provide the binary
compatibility you require. Sucking linc inside or ORBit2, as happened a
while back, seems to have generally gone pretty smoothly, but it is
probably not correct for distributions to stop shipping
if they wish to maintain full compatibility in their GNOME setup. This
is a subtle oversight, though, and yoy may wish to file a bug with
Mandrake about it.
