But after trying it I ran into the following problem: I copied BlockDist.x10 into my programs source directory, renamed the file and the class and removed the package x10.lang; declaration. Afterwards I added an import x10.array.Dist; because Dist is not available in the current package. But when I tried to compile a test program I got the following error message from the compiler: Could not find type "RectRegion". After adding the line import x10.array.RectRegion; another error shows up: Class x10.array.RectRegion is not accessible. I am using X10 v2.1.2 and the problem was the same both with the binary distribution for Mac OS and a self compiled version. Do you have any hints what the problem could be here?
