That's not how the R-admin manual describes how to do this.  Please try 
the way it does describe (and please try 2.4.0 RC rather than an old 
patched version of 2.3.1).

I am a bit puzzled: currently ACML is only available for Linux, Solaris 
and Windows, so where did you find a FreeBSD version?

Apparently libRlapack.so.  Is it there (in R_HOME/lib)?
