Install Qutip on Mac os x 10.10 via MacPorts - osx-yosemite

Question

I am not sure whether i can ask this question here.
I tried to install QuTips on my mac osx 10.10. Am following these two documentation for installation Qutip and MacPorts. Now am struggle to install gcc49.
When i execute this command sudo port install py34-scipy I got the following error
Admins-iMac-2:base admin$ sudo port install py27-scipy

I go and look for main.log file. At the end of this file i got below errors

Am not familiar with this. I cannot complete installation without this gcc49. Alternatively i install gcc48, but dosen't work for me. Every time it automatically tried ti install gcc49.
Anybody have any suggestion, it will be really appreciated.
