QML plugin doesn't work with shared dependencies

It's about Qt 4.7.3.

First of all, examples from qt distrib ( about C++ plugins for QML ) aren't working with prebuilt Qt libraries from official offline installer.

I can solve this problem by rebuilding Qt from source, but:

• In MacOs 10.5 & WinXp this plugin can't be loaded if shared libraries were used ( I used several boost libraries; an error raises from QML - "not found such component" )
• In Ubuntu 10.4 all work great with both types of libs.

Summary: I can create QML plugins only with static dependencies.
