Thanks for the bug description.

I tested your steps with Oracle Linux 6.4 (equivalent to RHEL 6.4)
with 2.6.32-358.14.1.el6.x86_64.  The build succeeded. I can show &
trace probes in the created binary.

Check that the dtrace -h & dtrace -G commands worked during your build
process.  Check zend_dtrace_gen.h is populated and that
zend_dtrace.d.lo is OK.  My zend_dtrace.d.lo has:

  # Generated by Makefile for libtool
  pic_object='.libs/zend_dtrace.d.o'
  non_pic_object='zend_dtrace.d.o'

Both referenced .o files were created during the build on my system.

I have head of issues with SystemTap support in some kernels,
depending on how the kernel was built and version of SystemTap.  I
would lean towards suspecting an issue with your kernel & SystemTap
versions.
