PHPEclipse: A User Guide Chapter 5 Addendum
DBG
It took a while, but DBG 2.13.1 has been released. You can get it at the DBG download site. This release officially covers up to PHP 4.4.2 and PHP 5.1.12. For the most current version of PHP 5, 5.1.4, DBG 2.13.1 should work without any problems.
Compiling Notes
One thing I neglected to include at the end of the DBG compile instructions was the location of dbg.so after you run deferizephp and make. dbg.so will be found inside the modules directory after you run the make command.
