Comment 11 for bug 168843

Right! latex and dvips are programs that can be found in the path by the OS and therefore inkscape. the existence of numpy can only reliably be detected by python. I think this is probably wishlist-able. We'll have to talk to Ted. Giving extensions more flexible means to declare if they can find all their deps is a really good idea. There are numerous problems trying to test even for simple deps in a reliable crossplatform manner.
