Just to let everybody know I have now compiled Molpro 2002.6 parallel. It  
turns out that the error I was getting when trying to link

/opt/intel_fc_80/lib/libcxa.so.6: undefined reference to `_ReadULEB'
/opt/intel_fc_80/lib/libcxa.so.6: undefined reference to `_ReadSLEB'

Was due to a conflicting package (libunwind-0.96-3) installed by SGI  
before delivery. This package was installed in a default location and as  
such the compiler was using this library instead of the correct library  
supplied with the compilers

i.e. it was using


instead of


If this problem occurs again, create a tar file with all files and  
symbolic links to libunwind* in a safe location away from any default  
paths (i.e. within a home directory). Remove all libunwind* files from  
their original location and recompile. If you feel the need you can  
restore the files back from the tar file, although you will need to repeat  
this process should you need to recompile any other package that requires  

I know this sounds like a bit of a hack but I was advised by SGI that the  
libunwind package is obsolete with ProPack 3 Service Pack 4 onwards.

Thankyou for all your help

Kind regards
