For example, when I want to add the IJulia package on my Mac OS julia 0.5 version, it says:
julia> using IJulia
INFO: Precompiling module IJulia.

Building Cairo and other packages are quite similar. This is really a bad experience, and I don’t know what to do besides post it somewhere. Is there anyone who can tell me that why this happens? I don’t think it is the problem of my Mac OS computer, for things are similar on another windows.
