hi there ... i am attempting to compile the linux software for the nostromo n52 (nostromo n50-1.2) , obviously the device works fine as is, but it would be nice to be able to use the profiles under *nix

this is the output on make:

since i am still somewhat retarded when it comes to compiling software, i am not sure what this is telling me. i am sure it is something simple that i should know, or should be able to find, but thus far i have not. any suggestions would be appreciated.
