OS X pip does not search .pypirc when installing packages?

Question

So, I created the ~ / .pypirc file

[distutils]
index-servers =
    custom

[custom]
repository: https://dist.secretrepo.com/simple/
username: user
password: 12345  

And added to my requirements.txt a version of the package that was only available in my regular pypi instance. However, no matter what I try, he will not take it? The same setup works fine in the Linux module, and not on OS X 10.10.3.
