Comment(by afb@…):

 Using "xcode3build" should work in theory, but there's a difference in
 practice:
 (NOTE: project ScriptExec was written by an older Xcode version (39) --
 temporarily upgrading it (without modifying project file))
 xcode3build[39572:4903] [IT] Exception while creating dependency graph for
 <context(0x1038932a0:'ScriptExec'):4 nodes (0 to eval), 2 commands>
 (ignored):
 ASSERTION FAILURE in
