Please do read the final line of your excerpt and do as it says ....

What is `Sun Studio'?  The R-admin manual does have references to what I
think is the same compiler, `Sun ONE Studio 7 Compiler Suite' (aka Forte
7) (possibly not the same version).  Forte 9 has also been used 
successfully, if -xopenmp=stubs was added to LDFLAGS (and that is in the 
R-admin manual for the imminent R 2.0.1).

Yes, well, not at the same clock speed.  Please do read the experience in 
the R-admin manual that you deny exists.

Either you are talking about a different product with a very similar name 
or you have missed a lot of useful information.
