Running ScalaZ3 on Mac - scala

Question

Running a program that uses ScalaZ3. This is on a Max with OS XAt run time I get an exception as follows
Could not find /lib-bin/libscalaz3.dylib
java.io.FileNotFoundException: Could not find /lib-bin/libscalaz3.dylib
at z3.Z3Wrapper.loadLib(Z3Wrapper.java:74)
at z3.Z3Wrapper.loadFromJar(Z3Wrapper.java:52)
at z3.Z3Wrapper.<clinit>(Z3Wrapper.java:32)
at z3.scala.Z3Config.<init>(Z3Config.scala:6)
Later I get a second stack trace
java.lang.UnsatisfiedLinkError: z3.Z3Wrapper.mkConfig()J
at z3.Z3Wrapper.mkConfig(Native Method)
at z3.scala.Z3Config.<init>(Z3Config.scala:6)
at thesis.z3option.Z3SessionCore$class.open(Z3SessionCore.scala:89)
I'm using the jar file at
jar-releases/64/scala-2.9.1/scalaz3-3.2.c.jar
in the github respository.
Edit: Here are the errors I got on step (3) of the set up process: sbt package
