removing a php5-pcre extension

[Zbigniew Szalbot]

Hello,

Now that pcre is included in the base installation, how do I remove it?

$ pkg_delete -nv php5-pcre-5.2.6_2
pkg_delete: package 'php5-pcre-5.2.6_2' is required by these other packages
and may not be deinstalled:
pear-1.7.2
pear-Auth-1.6.1
pear-Auth_SASL-1.0.2
pear-DB-1.7.13,1
pear-Log-1.10.1
pear-Mail_Mime-1.5.2,1
pear-Mail_mimeDecode-1.5.0
pear-Net_SMTP-1.3.0
pear-Net_Socket-1.0.8
pear-Pager-2.4.6
pecl-filter-0.11.0
php5-extensions-1.2
phpMyAdmin-3.1.0
smarty-2.6.19
pkg_delete: 1 package deletion(s) failed

Am I safe just deleting it? Or do I have to rebuild all the above listed ports?
Leaving it as is is probably not a good idea...

Thanks a lot for your input. If possible, I'd like to keep my system
clean without unnecessary ports.
