  It looks like you're trying to build Math::Int64 from the git repo. You'll
  need to install Module::CAPIMaker from CPAN in order to do this.

  It looks like your compiler doesn't support a 64-bit integer type (one of
  "int64_t" or "__int64"). One of these types is necessary to compile the
  Math::Int64 module.
