Methods not defined in Julia 0.4

[tcfuji]

I just installed the bleeding edge version of Julia and this package seems to have problems calling methods. For example:

model = [2.0, 1.0, -1.0]
X_train = randn(1000, 3)
y_train = int(map(x -> x > 0, X_train*model))
net = fit(X_train, y_train, logistic_regression_options())
sample = [1.0, 0.0, 0.0]
println("Ground truth: ", int(dot(sample,model)>0))
println("Prediction:   ", predict(net, sample))

gives this:

logistic_regression_options not defined
while loading In[3], in expression starting on line 4

This is the output when executing using MachineLearning:
