Extended regexps are those that egrep accepts; they can be clearer because they usually have less backslashes, but are a GNU extension and hence scripts that use them are not portable. See Extended regular expressions. So the fix is, presumably to add \ before () in the configure script at {{{ sed -r 's/(^| )([^ ])/\1-optl\2/g' }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9465 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
