OK - in general just ignore the below. I redid all the php stuff (make deinstall, make clean, make install clean) in the default php5, all good, same thing in php5-extensions, except this time I unchecked php-phar since it was not in the list of required modules. Everything went well. Sorry to potentially have wasted anybody's time, I might get the hang of this UNIX stuff (again) yet. The only mild concern is that the default version of php5 is deprecated, which will lead to an php-mbstrings STOP (unless is it overridden as I noted below) if php56 is attempted.

I get this installing the default php: "This port is deprecated; you may wish to reconsider installing it: PHP 5.4 is End of Life http://php.net/supported-versions.php. It is scheduled to be removed on or after 2016-01-15." Figuring I should go to the latest version then, I installed php56 and then progressed to php56-extensions. All good except that I found two of the extensions listed as required in the appendix for BSD are not present in the extensions setup to select. Those two are: php-spl php-pcre unfortunately the same issue is present in the base/default php-extensions as I went back there to see if they were present. I also get a STOP when php-mbstring comes up, saying it has vulnerabilities in the latest php56. I get a deprecated in the base/default php-extensions build. While compiling the default/base php5-extensions I get a STOP on building php5-phar. This is not in the list of required extensions but is listed as a dependency for php5-pdo (during its make). "===> php5-phar-5.4.45 has known vulnerabilities: php5-phar-5.4.45 is vulnerable: php -- multiple vulnerabilities CVE: CVE-2015-7804 CVE: CVE-2015-7803 WWW: https://vuxml.FreeBSD.org/freebsd/c1da8b75-6aef-11e5-9909-002590263bf5.html" So maybe three questions: 1. Should I use the deprecated (but seemingly default/base) php5 (5.4.x) or the newer php56? 2. Do the two missing extensions matter? if so, where do I get them? (see 2.a below!) 3. For the default php5-phar, am I safe setting 'DISABLE_VULNERABILITIES=yes' for make? I could do the same for the newer version and ignore the mbstring vulnerability. 2.a. Interestingly enough when I run php -m, it shows both SPL and pcre as loaded - I think they are actually in core for quite a long while now? perhaps they should be removed from the required list (unless it is assumed people are smarter than I and know they are part of core?)? So this whole thing is probably OK except for the issues with mbstring and phar vulnerabilities?
