Hi Krunal, first of all, welcome, and thanks for writing up your experience. I'm sorry that your install was as troublesome as it seems to have been.
To make things better for everyone, I would like to ask two favors of you: 1) If there is anything that we can do by default in PyCUDA to make a default Mac install less painful, please let me know. For example, should "-m32" be the default for Mac installs? 2) Next, while many people might eventually find this information on the mailing list, the Wiki (that you refer to) is designed to be the main place for up-to-date installation information. It's a wiki for a reason--to be edited! Don't be shy, and change that information where it's wrong, or augment it where additional info is needed. If I can be of any assistance, please let me know.
