Source: libdr-tarantool-perl
Version: 0.45-2
Severity: serious
Justification: fails to build from source

Dear Maintainer,

libdr-tarantool-perl's testsuite appears to non-deterministically fail, causing 
itself to FTBFS.

Using wall-clock time is inherently unreliable.

  #   Failed test 'total time less than 1 second'

  #     '8.6400101184845'
  #         <=
  #     '1'
  # Looks like you failed 1 test of 48.
