calculix-ccx fails to build

I found this in the install readme:

   If you like to use TAUCS as solver, install TAUCS in /usr/local/taucs
   (and lapack, blas and metis in /usr/local/taucs/external/lib/linux)
   and change the Makefile in
   /usr/local/CalculiX/ccx_2.14/src as follows:
   a) add "-I ../../../taucs/src -I ../../../taucs/build/linux -DTAUCS" to
      the CFLAGS (without double quotes)
   b) add 
       "../../../taucs/lib/linux/libtaucs.a \
        ../../../taucs/external/lib/linux/liblapack.a \
        ../../../taucs/external/lib/linux/libblas.a \
        ../../../taucs/external/lib/linux/libmetis.a \"
      to LIBS
   Notice that you only need lapack, blas and metis if you want to
   install TAUCS.
   Look at file tau.c and the documentation of TAUCS for details.
