As I see it, the problem with gprof is that to use it, you have to link the profiling library to the program you are running. You also have to compile your C files with a switch, but it's not difficult to tell Inline::C to do that.

I'm not sure how you can link the profiling library with perl. You may be able to achive this with the LINK config option of Inline::C, but I'm not sure if that would work. If it doesn't you have to relink perl with the profiling options given to the compiler, and install it.

Note also that the profiling option might have consequences on the linking other than just linking a library. You could try to figure these out by linking some program with and without profiling but with the -v or -### option passed to gcc (I wonder who gave this stupid name to the switch).

Update: This is all speculative of course. I don't have any experience with either Inline::C or gprof. It might be better to look for another profiler instead of gprof.
