 2568   -h, --help              display this help and exit
 2569       --help=short        display options specific to this package
 2570       --help=recursive    display the short help of all the included packages
 2571   -V, --version           display version information and exit
 2572   -q, --quiet, --silent   do not print \`checking ...' messages
 2573       --cache-file=FILE   cache test results in FILE [disabled]
 2574   -C, --config-cache      alias for \`--cache-file=config.cache'
 2575   -n, --no-create         do not create output files
 2576       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 2577 
 2578 Installation directories:
 2579   --prefix=PREFIX         install architecture-independent files in PREFIX
 2580                           [$ac_default_prefix]
 2581   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 2582                           [PREFIX]
 2583 
 2584 By default, \`make install' will install all the files in
 2585 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 2586 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 2587 for instance \`--prefix=\$HOME'.

 2693 Some influential environment variables:
 2694   CC          C compiler command
 2695   CFLAGS      C compiler flags
 2696   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 2697               nonstandard directory <lib dir>
 2698   LIBS        libraries to pass to the linker, e.g. -l<library>
 2699   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 2700               you have headers in a nonstandard directory <include dir>
 2701   CXX         C++ compiler command
 2702   CXXFLAGS    C++ compiler flags
 2703   CPP         C preprocessor
 2704   LT_SYS_LIBRARY_PATH
 2705               User-defined run-time library search path.
 2706   CXXCPP      C++ preprocessor
 2707 
 2708 Use these variables to override the choices made by `configure' or to help
 2709 it to find libraries and programs with nonstandard names/locations.

 4612 on the command line, even when the '-f' option is present.  This is contrary
 4613 to the behaviour of most rm programs out there, and not conforming with
 4614 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 4615

 4617 of your $PATH and any error possibly output before this message.  This
