Dear.

I have tried to install gpaw-1.3.0, the install has shown successful, 
but when running, it shows:

=============================

  ./gpaw
Traceback (most recent call last):

=============================

The scalapack and lapack are builded with Intel compiler(13.0.0, gcc 
4.4.7).

Part of customize.py:

# LibXC:
# In order to link libxc installed in a non-standard location
# (e.g.: configure --prefix=/home/user/libxc-2.0.1-1), use:

     if 'xc' in libraries:
         libraries.remove('xc')

# - dynamic linking (requires rpath or setting LD_LIBRARY_PATH at runtime):

     include_dirs += ['/home/longjun01/libxc-2.0.1/include']
     library_dirs += ['/home/longjun01/libxc-2.0.1/lib']

         libraries.append('xc')

[longjun01 at ln3%th2 ~]$ echo $LD_LIBRARY_PATH

[longjun01 at ln3%th2 ~]$ grep _gfortran_concat_string ~/local/lib/*.a
Binary file /home/longjun01/local/lib/liblapack.a matches

Thank you very much.
