If configure does not work on your system and you have a reasonably
up-to-date set of tools, running ./autogen.sh before running ./configure
may fix the problem. You can also run the individual commands in
autogen.sh with the --force option, if supported by your version of
the tools. To be really sure that you aren't using any of the included

./configure [--prefix=/path] [other options]
make
make install
make check

"scripts" directory
