Problem with upgrading php5-pcre and php5-mysql

[KernelPanic]

My upgrade to php5.2.6 went ok. But both of these ports are suffering the same error of a missing 'shtool'

Stop in /usr/ports/devel/php5-pcre.

It appears as if shtool is missing but I don't know why it is missing or how to get the port to create that file.
