That's not the point I was trying to make.  My point was that _the package
shows how to build on all supported platforms_ and hence provides an
"existence proof". So you should download _it_ and see if you can build it.
You should be able too---and then be able to carry what it does over to your
project. 

And as James said by now too, it may be as simple as setting the required env
var.

Cheers, Dirk
