Issues when setting up DeepLearning4J in Mac OSX

I got the following errors when I was trying out DeepLearning4J example with Deep Belief Nets (DBNs) in Mac OSX 10.10 (Yosemite)
It is being said that Jblas is already available in Mac OSX, but still I got some errors with that. 

Jblas is a pre-requisite for setting up DeepLearning4J. 


DeepLearning4J uses ND4J to enable scientific computing with N-Dimentional arrays for Java. ND4J works on several backend linear algebra libraries (execution support with CPU or GPU). Jblas is one Java backend used in  DeepLearning4J for the required matrix operations. 

NoAvailableBackendException ND4J 

Solution: Add the following dependancy

org.nd4j
nd4j-jblas
0.4-rc0

java.lang.ClassNotFoundException: org.jblas.NativeBlas 

Solution: Add the following dependancy

  org.jblas
  jblas
  1.2.4
