      (most of this text was written using google translate.
 english is not good at me. so there's a possibility that the meaning
is not transmitted.)

there may be unnecessary operation and defects.
however, it is forced by this operation, but it have confirmed the
operation of the tutorial examples.

* step 0, dependencies.
  gmp           5.0.1
  cln (gmp)     1.3.3
  gcc           4.7.2
  ld            2.23.1
  m4            1.4.16

  python        2.7.3
  bison         2.4.2
  flex          2.5.35

* step 1.
  $ git clone git://www.ginac.de/ginac.git

* step 2, modify the 'ginac/config/config.rpath'.

* step 3.
  $ cd ginac

* step 4, modify the 'ginac/configure'.

* step 5, modify the 'ginsh/ginsh_lexer.lpp'.
