That is a linker error.
Now, if look at the linker statement from above (wrapped to one line here)
gfortran -shared -L/usr/local/lib -o lbfgsbr.so dcsrch.o dcstep.o mtlnsrch.o
-lgfortran
you see that is contains no linking of any (system) C++ library.
So no wonder the symbol is missing.
You could try to start from a working package (Rcpp.package.skeleton() can
help) then add your Fortran file(s), and/or set LD in src/Makevars explicitly.
