TGE 1.5.2 + Motion Blur

Hey guys,

I need some help.
I'm doing a build with TGE 1.5.2 and the Motion Blur resource
(http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=5686)
But i'm getting some compile errors.

The same build on windows works fine, but on Linux i get this:

--> Linking out.GCC4.RELEASE/torqueDemo.bin
out.GCC4.RELEASE/gui/core/guiTSControl.obj: In function 'GuiTSCtrl::onRender(Point2I, RectI const&)':

collect2: ld returned 1 exit status
make[1]: *** [out.GCC4.RELEASE/torqueDemo.bin] Error 1
make: *** [default] Error 2

Other info:
gcc version 4.1.2
xubuntu 7.04, Feisty Fawn

Any ideas?

Thanks in advance!
