[Rd] Profiling C functions called from R.

I am working on an R package which includes some C routines. I would
like to profile the C routines (built with GCC under Debian Linux). I
tried running R with
and executing functions that would invoke the code therein. The code
takes about twice as long to run with LD_PROFILE set than without, so I
am guessing that profiling is taking place. However, gmon.out is not
generated (or at least I can't find it anywhere on the filesystem).
Has anyone been able to profile shared libraries built for R in Linux?
Thank you in advance,
