Text/Show/ByteString/Integer.hs:27:1: Warning:
    The import of ‘GHC.Num’ is redundant
      except perhaps to import instances from ‘GHC.Num’
    To import instances alone, use: import GHC.Num()

Configuring helics-0.5.1...
setup: Missing dependencies on foreign libraries:
* Missing C libraries: newrelic-collector-client, newrelic-transaction,
newrelic-common
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
Failed to install helics-0.5.1
cabal: Error: some packages failed to install:
helics-0.5.1 failed during the configure step. The exception was:
