Does anyone have any advice about profiling C/C++ code in a package
under R? Does R need to be built specially for this to work?
The FAQ has some entries about profiling but they cover R level
profiling; I'm try to get at the C++ code I've written that is called
from R.
Primary target is Mac OS
The last time I tried I didn't have much luck. The gprof manual I could
find seems to indicate that it can not profile code that are dynamically
loaded. (I was trying on Linux.) The R source seems to hint otherwise.
I'd very much appreciate pointers as well.

Some more information.
1) Whether gprof works is system-specific. Solaris says in man gprof
64-bit profiling
64-bit profiling may be used freely with dynamically linked
executables, and profiling information is collected for the
shared objects if the objects are compiled
