libbit-vector-perl 7.4-1build6 (riscv64 binary) in ubuntu focal

 Bit::Vector is a module that allows you to handle bit vectors, integer sets,
 "big integer arithmetic" and boolean matrices, all of arbitrary sizes. It is
 efficient (in terms of algorithmic complexity) and therefore fast (in terms
 of execution speed). It also provides overloaded operators for ease of use.
