libghc-mmap-prof 0.5.8-3 (arm64 binary) in ubuntu trusty

 This library provides a wrapper to mmap(2) or MapViewOfFile, allowing files or
 devices to be lazily loaded into memory as strict or lazy ByteStrings,
 ForeignPtrs or plain Ptrs, using the virtual memory subsystem to do on-demand
 loading. Modifications are also supported.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
