[R] Loading Fortran code with NAG subroutines

Dear R-users,

System specs
R-1.2.2 under Unix Sun Solaris 2.7
Nag Fortran library Mark 18

when I try to dynload a Fortran77 code (compiled using R CMD SHLIB) which contains calls to NAG subroutines (nagsymbols) I get the following error message

ld.so.1: /opt/rhome/R-1.2.2/bin/R.bin: fatal: relocation error: file /path/to/myfile.so: symbol nagsymbol_:referenced symbol not found

I changed the default compilation flags in rhome/Makeconf (i.e. adding -L/path/to/nablib.so, -lnag) without success.
Any suggestions on what might be missing?

Thanks in advance,
