[Paraview] cannot link Plugin based on Paraview 3.10.1 using Qt 4.7.4 on Mac OS OX 10.6.8 | gcc 4.2.1 | Xcode 4.0 | CMake 2.8-2 (x86_64 is on)

[nikos yiotis]

My plugin builds OK if i choose a static library, but of course i cannot
load it into PV.
Can anyone decipher the message below when i choose to build a shared lib,
that is *.dylib?
Thanks

Paraview 3.10.1 using Qt 4.7.4 on Mac OS OX 10.6.8 | gcc 4.2.1 | CMake 2.8-2
