Gentlemen, make --dry-run is booby trapped to still execute commands:
$ (cd Documentation; make --dry-run); find -mtime -1 -type f
./Documentation/doc.dep
./GIT-VERSION-FILE
Forgot $(MAKEFLAGS)? (info "(make)Options/Recursion").
By the way, why would an offline make need
/bin/sh: curl-config: command not found
