mask not working in standalone app

[haelbichalex]

When I built my app and transferred it to another mac, I can still see my layer, but my mask is not applied to it. My layer is a png image. On my mac where I developed the app, the mask is working correctly.
I am using openframeworks 0.9.8.

[ error ] ofShader: setupShaderFromFile(): couldn't load GL_VERTEX_SHADER shader  from "../../../../../addons/ofxLayerMask/src/shader/alphaMask_GL2.vert"
[ error ] ofShader: setupShaderFromFile(): couldn't load GL_FRAGMENT_SHADER shader  from "../../../../../addons/ofxLayerMask/src/shader/alphaMask_GL2.frag"
[ error ] ofShader: linkProgram(): trying to link GLSL program, but no shaders created yet

Seems like this line is the problem
