Read where?  It's incorrect information and only used for Fortran linking.

You should have a file called Makevars in the directory from which 
you are doing the building, defining PKG_LIBS, maybe

PKG_LIBS="-L/path/to/libgsl -lgsl"

in the same way as you would for a package: see `Writing R Extensions'.
I don't think that is documented anywere, though.

Dear R-list people, 
I asked a similar question a few hours before. I will try to be more specific. 
We like to add the GSL library to the file SHLIB in order to make it possible to
run the C code using GSL functions from R.
We read that the path to the libgsl.a should be added to the line
shlib_libadd=' '  in the file SHLIB but it does not work on our system.
Dyn.load fails with error "referenced symbol <symbolname> not
found". What is wrong?
We will much appreciate any help on this.

We are using R-1.9.1 on Unix.
