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:

  [../build_cli.sh: line 87: rustup: command not found]: [This is why build exited. Log indicates that there was an attempt to set alias rustup=rustup-init but did not work for some reason]
=============
[+ alias rustup=rustup-init]: [This alias did not apply properly, or got discarded later]

Issue: rustup package has rustup-init binary name therefore exits with 'command not found'
Resolution: Instead of calling 'rustup target add' try 'rustup-init target add'
