Er? What is an "emulated Opteron" machine? Opterons are 64 bit. > It should work out of the box on an Opteron Linux systen: it does for > example on FC3 and SuSE 9.x.

Only if you want to include hardcore optimized BLAS or do not like the performance hit of having R as a shared library do you need to compile at all. -- O__ ---- Peter Dalgaard Øster Farimagsgade 5, Entr.B c/ /'_ --- Dept. of Biostatistics PO Box 2099, 1014 Cph.
