Unfortunately this is not an ideal solution, as its difficult to isolate
the gprof message for the C++ code and identify that with a part of a
script file. Also to use gprof octave has to be compiled with
"--enable-static --disable-shared --disable-dl" which means no external
oct-files. No gprof is more a tool for Octave developers to identify
slow bits of the C++ code itself rather than a generic Octave profiler.
