gnuplot on FreeBSD

[Dhiman B. <dh...@ca...>]

The following is a summary of what one has to do to hack gnuplot4.1's prepare
to work on FreeBSD; thanks to Dan Andersen who made it work:

in the script 'prepare':

change all instances of 'make' with gmake.  Freebsd has it's
own BSDesque make program.  The makefiles in gnuplot use features
unavailable in bsd make, so gnu make must be used.

work around FreeBSD's choice of naming autoconf and
automake binaries with version numbers.  You can either modify the
prepare script directly, or create a ~/bin directory and create symlinks
like ~/bin/aclocal -> /usr/local/bin/aclocal19
