Calculix lib error

Hello,

when trying ro start calculix 2.4 i get the following error:
ccx_2.4: symbol lookup error: ccx_2.4: undefined symbol: _gfortran_internal_malloc

i'm using caelinux 2011 and the calculix executable from the webside. i made a symbolic link for the libgfortran.so.2 (otherwise calculix would just say that the lib is missing).
Does anyone know how to solve this or where to get the libgfortran.so.2 file?
