The step for configuration works correctly and gives a makefile.

On running `./make` the following traceback is produced:

```
$ make                                                                                                         
-----------------------------------------------
Modules/Setup.dist is newer than Modules/Setup;
check to make sure you have all the updates you
need in your Modules/Setup file.
Usually, copying Modules/Setup.dist to Modules/Setup will work.

```

This is strange.

I cloned the repo again at some other location, and I can build it successfully.

In my older clone, however, it shows me this error, despite running a `make clean`.

Any idea on what is the problem here?

Sometime, you need to run `make distclean` or `git clean -fdx` to remove wrong caches.
