[Rd] Rinternals.h and undefined symbols

I'm trying to register my native routines using R_registerRoutines 
(...). I can compile the code, but the loader cannot resolve the symbol:

undefined symbol:  

$ nm bgx.Rcheck/bgx/libs/bgx.so | grep R_registerRoutines

Why does it have this funny name? If I look at libR.so, I get an  
ordinary symbol name:

$ nm ~/lib64/R/lib/libR.so | grep R_registerRoutines
0000000000032f80 T R_registerRoutines

I get normal symbol names for R functions not in Rinternals.h and  
there is no problem there. For example:

nm bgx.Rcheck/bgx/libs/bgx.so | grep Rprintf
                  U Rprintf

$ nm ~/lib64/R/lib/libR.so  | grep Rprintf
0000000000129690 T Rprintf

The shared library dependencies are also fine:

$ ldd bgx.Rcheck/bgx/libs/bgx.so
         libR.so => /home/et04/lib64/R/lib/libR.so (0x0000002a95676000)
         libstdc++.so.6 => /usr/lib64/libstdc++.so.6  
         libm.so.6 => /lib64/tls/libm.so.6 (0x0000002a95c70000)
         libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000002a95df7000)
         libc.so.6 => /lib64/tls/libc.so.6 (0x0000002a95f02000)
         libRblas.so => /home/et04/lib64/R/lib/libRblas.so  
         libg2c.so.0 => /usr/lib64/libg2c.so.0 (0x0000002a96262000)
         libreadline.so.4 => /usr/lib64/libreadline.so.4  
         libncurses.so.5 => /usr/lib64/libncurses.so.5  
         libdl.so.2 => /lib64/libdl.so.2 (0x0000002a96618000)
         /lib64/ld-linux-x86-64.so.2 (0x000000552aaaa000)

My LD_LIBRARY_PATH environmental variable is set appropriately.

Any ideas?
