Are you > saying that X support is less crucial than image support? X development libraries are required before we even look for these image libraries. There is no such thing as image support without X, except for W32 and OSX, and those platforms don't use the image libraries we check for. As stated earlier, it is probably a mistake to compile for X without image support. Also, as has been said before, it is hard to look for X support if the development libraries for X is missing, even if we use the heuristic posted by David Kastrup. Crosscompiling is one problem.
