downgrade php5

[doug schmidt]

After upgrading to php 5.3.2, we have a few in house applications that
broke and our developers will not be able to work this out for at
least another week or so, so I need to downgrade back to 5.2.12 in the
mean time.

I've used portdowngrade lang/php5 and lang/php5-extensions, during
make install of php5-extensions it fails on php5-filter

Since some ports have been removed as they are bundled with 5.3.2, how
can I get this downgraded properly. (devel/php5-pcre is no longer
in the ports tree).

thanks.
