Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

]: [This part indicated that during %prep phase the upstream archive was extracted, but it does not contained `SuperNOVAS-1.1.1` directory.]

Issue: During %prep phase you usually use %setup macro to extract upstream archive and cd into top-level directory. By default the directory is assumed to be %name-%version. But some upstream archive has different structure. In such case the build fails unless you tell %setup macro what to do.
Resolution: Check what is inside of the tarball and check what arguments to %setup macro is suitable for you. The relevant documentation is http://ftp.rpm.org/max-rpm/s1-rpm-inside-macros.html
