 Looking for files not under the current tree in combination with copying
 to build/ seems to be problematic. The whole design of scons seems to be
 based on the individual environments being independent of each other. I
 tried env.Depends without success. Maybe the solution is a scons

 This patch https://github.com/rgommers/scipy/tree/arpack-crashes fails
 because the build/ dir is populated package by package. isolve happens to
 be built before arpack, so the build/scons/scipy/sparse/linalg/eigen dir
 doesn't yet exist. If I manually copy it over and restart the build it
 works. Then all segfaults are solved.

 David, perhaps you know what the best solution is?
