Yes, I do.
I have WITHOUT_PROFILE='yes' set in /etc/make.conf for a normal
buildworld. I then comment it out and specifically build libc_p.a
and libm_p.a. These are the only profiled libraries I use.
Why? Because adding -pg to the gfortran command line is sufficient
to getting profiling information for long running numerically
intensive codes. 'gfortran -pg', of course, loosk for libc_p.a
