Have you had any luck porting the dtrace bits to php 5.3.8? I 
successfully managed to "port" (or at least merge) the integrated dtrace 
bits from PHP 5.3.99 (the codename for php 6 I think) into 5.3.8, 
however it bombs out in the install stage at the last minute:

I thought perhaps my port of the code had gone wrong, but then I tried 
building php 5.3.99 itself, and it had exactly the same issue.

I have tried with both gcc 3.4.3, gcc 4.5.2, and Sun Studio and always 
encounter the same problem.

I contacted what I think is the main author of the DTrace patch in PHP 
5.3.99 (David Soria Parra) and he replied to my first email but hasn't 
gotten back to me yet after I provided more info to him.

It would be interesting to see if you can get php 5.3.99 to successfully 
build with dtrace enabled. Instructions are here:

I might try older revisions from the subversion repo if I find time.

Cheers,
