libmfwba.so: cannot open shared object file

I am getting following error when writing a sample program in C++ for qt and gsteamer on nitrogen6X (imx6Q) board. I am using timesys mid march 2013 release.

While this works with gst-launch pipeline.

Any quick suggestion is highly appreciated.

Thanks

Can you please check with the prebuilt images (rootfs) from freescale.com. Whether the same problem is reproducible?
