IPC::Cmd and Time::Piece have been in core since 5.9.5 which is very nearly a decade ago. Many dists don't mention core modules as dependencies, perhaps because the authors (erroneously) assume that everyone has the core installed by default. Module::Build used to be in core and it's possible that the author of Marpa::R2 did not notice when it was dropped from core.

Which version of Perl are you running and on which operating system?
