Fixed that by downloading a version 2.20.51 dated 24th of October.

Unfortunately, while it builds without a hitch, it apparently cannot 
cope with Fortran COMMON blocks:

/usr/snp/lib/gcc/x86_64-unknown-linux-gnu/4.5.0/../../../../x86_64-unknown-linux-gnu/bin/ld: 
error: /scratch/hirlam/hl_home/EXP/lib/src/linuxgfortran/lib/port.a: 
multiple definition of casihl_
/usr/snp/lib/gcc/x86_64-unknown-linux-gnu/4.5.0/../../../../x86_64-unknown-linux-gnu/bin/ld:
