R - WARNING: cannot run mixed C/Fortran code (then exits)

Build environment

• Sun Ultra 27 3.333 GHz Intel Xeon. 12 GB RAM
• OpenSolaris 2009.06 snv_111b X86
• Sage 4.3.1.alpha1 (with a few packages hacked to work on 64-bit)
• gcc 4.3.4 configured with Sun linker and GNU assembler from binutils version 2.20.
• 64-bit build. SAGE64 was set to yes, plus various other tricks to get -m64 into packages.

I'm not sure whether this is still valid. Could be.
