So, you've clearly enabled the DTRACE option, which should work as
you're compiling on a supported architecture (amd64) and OS version
(11.0).  However, dtrace capabilities can be a tricky thing to compile
in properly.

Have you done a 'make clean' since enabling the DTRACE option?  You need
to recompile everything as one of the effects of turning on DTRACE is to
enable some conditionally included blocks of code.

Are you using poudriere or similar, that compiles software in a separate
jail?  If so, and the jail doesn't contain a copy of the kernel, then
dtrace will likely fail.  I believe you should be able to get round this
by adding -xnolibs to the dtrace command line -- unfortunately it seems
this version of perl doesn't have an equivalent to DTRACEFLAGS that I
can see, so you might have to resort to hacking on the Makefiles in the
perl sources.

	Cheers,
