Used SUP yesterday to update pkgsrc on a 1.5.2 system.  PHP4 builds OK,
and then towards (I assume) the end of the installation:  

Installing build environment
Installing program: phpize
Installing program: php-config
Installing program: pear
Installing program: pearize
Installing program: phptar
Installing program: phpextdist
install -d -o root -g wheel -m 555 /usr/pkg/libexec/cgi-bin
/bin/ln -sf ../../bin/php /usr/pkg/libexec/cgi-bin/php
install -d -o root -g wheel -m 555 /usr/pkg/share/examples/php
cd /usr/pkgsrc/www/php4/work/php-4.2.3; install -c -o root -g wheel -m 444
php.ini-dist php.ini-recommended /usr/pkg/share/examples/php
install -d -o root -g wheel -m 555 /usr/pkg/share/php
install -c -o root -g wheel -m 444
/usr/pkgsrc/www/php4/work/php-4.2.3/php.gif /usr/pkg/share/php
Installing configuration files for php-4.2.3:

    /usr/pkg/etc/php.ini already exists, example file is
        /usr/pkg/share/examples/php/php.ini-recommended

=========================================================================

You may wish to customize the following files for php-4.2.3:

        /usr/pkg/etc/php.ini
=========================================================================
==
Unexpected argument: 
*** Error code 1


Where do I look?  (I don't use PHP; I'm installing it for someone who
does.)  

Thanks.
