Where did you install the MARS libraries?
Did you follow the README section "Building Source"?
If not try doing exactly what it says to do:

32-bit host
---------------------
[mars-lib]$ ./configure --host=ppu --libdir="/usr/lib"
[mars-lib]$ make HOST_FLAGS=-m32

64-bit host
---------------------
[mars-lib]$ ./configure --host=ppu --libdir="/usr/lib64"
[mars-lib]$ make HOST_FLAGS=-m64

then make install (probably need to be root)

I know someone else has mentioned problems trying to build the test and
sample sources when installing MARS to a non-standard path.
Eventually this should all be cleaned up.

But the instructions above should work for you.
