about ports reinstall

[Lila]

Hi,

The php4 ports that I installed did not work with mysql,
it seems like it never able to configure to work with mysql.
No mysql info can be found with phpinfo().

I tried to reinstall php4 many times but no luck for me.
I want to ask is there a way to completely remove the
installed ports and related deps so that I can do a very
clean install of php4 and maybe with apache and mysql.

Thanks!

Regards,
