  <listitem><para>GNU Make.</para></listitem>

  <listitem><para>A version of GCC or Clang that supports C++11.</para></listitem>

  <listitem><para>Perl 5.8 or higher.</para></listitem>

  <listitem><para><command>pkg-config</command> to locate
  dependencies.  If your distribution does not provide it, you can get
  it from <link
  xlink:href="http://www.freedesktop.org/wiki/Software/pkg-config"
  />.</para></listitem>

  <listitem><para>The bzip2 compressor program and the
  <literal>libbz2</literal> library.  Thus you must have bzip2
  installed, including development headers and libraries.  If your
  distribution does not provide these, you can obtain bzip2 from <link
  xlink:href="http://www.bzip.org/"/>.</para></listitem>

  <listitem><para>The SQLite embedded database library, version 3.6.19
  or higher.  If your distribution does not provide it, please install
  it from <link xlink:href="http://www.sqlite.org/" />.</para></listitem>

  <listitem><para>The Perl DBI, DBD::SQLite, and WWW::Curl libraries, which are
  available from <link
  xlink:href="http://search.cpan.org/">CPAN</link> if your
  distribution does not provide them.</para></listitem>

  <listitem><para>The <link
  xlink:href="http://www.hboehm.info/gc/">Boehm
  garbage collector</link> to reduce the evaluator’s memory
  consumption (optional).  To enable it, install
  <literal>pkgconfig</literal> and the Boehm garbage collector, and
  pass the flag <option>--enable-gc</option> to
  <command>configure</command>.</para></listitem>

  <listitem><para>The <command>xmllint</command> and
  <command>xsltproc</command> programs to build this manual and the
  man-pages.  These are part of the <literal>libxml2</literal> and
  <literal>libxslt</literal> packages, respectively.  You also need
  the <link
  xlink:href="http://docbook.sourceforge.net/projects/xsl/">DocBook
  XSL stylesheets</link> and optionally the <link
  xlink:href="http://www.docbook.org/schemas/5x"> DocBook 5.0 RELAX NG
  schemas</link>.  Note that these are only required if you modify the
  manual sources or when you are building from the Git
  repository.</para></listitem>

  <listitem><para>Recent versions of Bison and Flex to build the
  parser.  (This is because Nix needs GLR support in Bison and
  reentrancy support in Flex.)  For Bison, you need version 2.6, which
  can be obtained from the <link
  xlink:href="ftp://alpha.gnu.org/pub/gnu/bison">GNU FTP
  server</link>.  For Flex, you need version 2.5.35, which is
  available on <link
  xlink:href="http://lex.sourceforge.net/">SourceForge</link>.
  Slightly older versions may also work, but ancient versions like the
  ubiquitous 2.5.4a won't.  Note that these are only required if you
  modify the parser or when you are building from the Git
  repository.</para></listitem>
