the cause of this is this line in ghc’s postinst: if $libdir/bin/ghc --info | grep -q '"Have interpreter","YES"' ; then The reason is that grep -q will quit after the match, so for subsequent lines, ghc’s stout is closed. hPutChar on a closed file descriptor gives SIGPIPE. I guess this is an upstream bug, which should handle SIGPIPE more gracefully. I recall some discussion about this on haskell-cafe, but am offline at the moment, so I cannot investigate. A quick fix might be writing if $libdir/bin/ghc --info | grep '"Have interpreter","YES"' >/dev/null ; then instead.
