[Haskell-cafe] compiling ghc-6.8.3: unrecognized command line option "-fconfigure-option=" (SOLVED)

[Poor Yorick]

For anyone who might experience the same problem...

Intalling ghc-6.8.3, the following error occurred:

It turned out that trailing whitespace in the LDFLAGS and CPPFLAGS environment variables were causing these problems.  see libraries/Makfile:

    # We rely on all the CONFIGURE_ARGS being quoted with '...', and there
    # being no 's inside the values.
    FLAGGED_CONFIGURE_ARGS = $(subst $(space)',\
                                     $(space)--configure-option=',\
                                     $(space)$(CONFIGURE_ARGS))
