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:

  [Problem: cannot install the best candidate for the job
  - nothing provides nim-srpm-macros needed by redhat-rpm-config-178-1.fc34.noarch from copr_xxmitsu_llvm_priority_10
]: [nim-srpm-macros is needed by redhat-rpm-config-178-1.fc34.noarch but is not available from source]
=============
[You can try to add to command line:
  --no-best to not limit the transaction to the best candidates
  --skip-broken to skip uninstallable packages]: [--no-best and --skip-broken are probable workarounds but their usage is not optimal]

Issue: dnf5 command fails since nim-srpm-macros is not avaialble
Resolution: Build nim-srpm-macros from source if not available using the build terminal
