cd /usr/bin/scp && ln -s /usr/local/bin/scp

Ну так scp есть и там, и там.

Options:
  -D debug_level_spec  Set debug level.
  -d                   Force target to be a directory.
  -q                   Make scp quiet (only fatal errors are displayed).
  -Q                   Don't show progress indicator.
  -p                   Preserve file attributes and timestamps.
  -u                   Remove source files after copying.
  -B                   Sets batch-mode on.
  -r                   Recurse subdirectories.

  -b                   Define maximum buffer size for one request (default 32768 bytes).
  -N                   Define maximum number of concurrent requests (default 10).
