Perl now supports DTrace out of the box
By Kai Seidler on Aug 26, 2009
Just scanned through the Perl 5.10.1 delta document and found this promising statement:
Some support for DTrace has been added. See "DTrace support" in INSTALL.
And according INSTALL all you need to do is to add -Dusedtrace to Configure and your Perl will be ready to DTrace. Very cool.
