Hello,

 I'm currently rebuilding one of our webservers, and facing a problem: 

[amelie:/usr/pkgsrc/databases/php-pdo_pgsql]# make

*** Error code 1

Alas, php-pdo is installed:

[amelie:/usr/pkgsrc/databases/php-pdo_pgsql]# pkg_info | grep php
php-5.1.2           PHP Hypertext Preprocessor version 5
ap-php-5.1.2nb5     Apache (apache13) module for PHP5
php-pdo-5.1.2.1.0.2nb1 PHP extension for PHP Data Objects (base)

And the appropriate directory does contain stuff: 

[amelie:/usr/pkgsrc/databases/php-pdo_pgsql]# ls /usr/pkg/include/php/ext
date      hash      libxml    pcre      pdo       session   standard  xml

I'm stymied.

What is going wrong? 

Thank you,
 Konrad
