Jake: I also have volunteered some of my time to this community. E.g. I had to adapt Gaston to Windows systems, and documented the effort.
The description of a package listed in the Julia website ought to contain notes that a package was only tested under a certain OS, and should not be assumed to work elsewhere. I spent many hours with packages, which do not tell this, and just don't work in my system. In the CUDA case: what is libcuda? Is it the CUDA runtime shared library? What functions are expected and used from it? Adding these notes should not take more than a few minutes of the author's time, but saves a lot of frustration and time of a potential user. The lack of responses to my original question indicates that there are no Windows users of CUDA, even though having a Windows CUDA package could have been really useful: many of us have modern NVIDIA graphic cards, which support CUDA, and speed up certain algorithms by orders of magnitude. Now I may end up writing my own CUDA module, which is duplicating work.
