>Description:
I was running nginx / php5 for quite some time, and switched back to apache 
now, using www/ap-php for php-content. At least it was my intention.

I am using pkgsrc-current with nightly updates from CVS on the above mentioned 
system.

Assuming that ap-php would use the setting defined by PKG_OPTIONS.php, I did 
not really take a look at the package. This of course lead to several problems 
with the modules, as I use maintainer-zts on lang/php5. I noticed those 
problems, and in search of a solution, I did a 

make show-options

in www/ap-php. It revealed that www/ap-php used the variable 
PKG_OPTIONS.ap22-php5, so I set that in /etc/mk.conf and recompiled. Almost 
immediately, I noticed that PKG_OPTIONS.ap22-php5 was still shown as empty, the 
parameters used were still the defaults. I tried several combinations from 
PKG_OPTIONS.ap-php to PKG_OPTIONS.ap22-php5 without success.
I then used PKG_DEFAULT_OPTIONS within the Makefile directly, which finally 
"solved" my problem.
Since this cannot be a real solution to the problem, a fix is required badly. 
>How-To-Repeat:
Simply run make show-options, after the PKG_OPTIONS.ap22-php5 has been defined 
in /etc/mk.conf
