deleted a bunch of php4 files under freebsd5.3, what to do?

I screwed up! Now thats out of the way. I used the command "rm -rf" to delete files like php.ini, the directory ...../lib/php and extension.ini. Please don't ask why, I hope it will suffice to say I'm a newbie. Like you hadn't figured that one out already :-) PHP4 was installed as a part of the IMP ports installation. I have trieded to "deinstall" IMP, hoping it would remove all the packages it installed, but of course not. I have tried "pkg_delete php4...." no luck, as there were about 40 packages depending on php4... Is there a php4-4.3.11_1 port that I can install/reinstall, I have looked under /usr/ports/www/ but there seems to be different php, but non just stating php4 or similar. Any help is apreciated.
