develop branch build errors

I pulled the latest from the develop branch and now I'm getting build errors:

./../_build/linux/x86_64/debug/libkernel.a(idraw.o): In function `MCImage::get_rep_and_transform(MCImageRep*&, bool&, MCGAffineTransform&)':
/home/mwieder/livecode/engine/./src/idraw.cpp:46: undefined reference to `MCResampledImageRep::Matches(float, float, MCImageRep const*)'

...solved by adding image_rep_resampled.cpp to the Makefiles.
