Well "it worked me for" but a better approach entirely outside of your
package may be to take

  edd at max:~$ grep shared /etc/R/Makeconf 
  DYLIB_LDFLAGS = -shared -fopenmp# $(CFLAGS) $(CPICFLAGS)
  SHLIB_CXXLDFLAGS = -shared
  SHLIB_CXX1XLDFLAGS = -shared
  SHLIB_FCLDFLAGS = -shared
  SHLIB_LDFLAGS = -shared# $(CFLAGS) $(CPICFLAGS)
  edd at max:~$ 

and add them to ~/.R/Makevars as

  DYLIB_LDFLAGS = -shared -fopenmp# $(CFLAGS) $(CPICFLAGS)
  SHLIB_CXXLDFLAGS = -shared
  SHLIB_CXX1XLDFLAGS = -shared
  SHLIB_FCLDFLAGS = -shared
  SHLIB_LDFLAGS = -shared# $(CFLAGS) $(CPICFLAGS)

When I do that without/with the change I get

  edd at max:/tmp/ffstream$ ls -lh ffstream*/src/ffstream.so
  -rwxrwxr-x 1 edd edd 9.0M Nov 26 07:52 ffstream.orig/src/ffstream.so
  -rwxrwxr-x 1 edd edd 734K Nov 26 07:52 ffstream/src/ffstream.so
  edd at max:/tmp/ffstream$ 

I think it is an issue worth raising with on r-devel and I may do so.

Dirk
