Problem compiling libgd as selfcontained PHP-Extension

Hello, I'm trying to compile the php-gd-extension as selfcontained module to use it via dl() on the server of an provider who doesn't have gd-support compiled in. I copied the contents of ext/gd to another directory, executed phpize and ./configure produces following output: :~/php_ext_selfcontained/gd # ./configure loading cache ./config.cache checking for gcc... gcc checking whether the C compiler (gcc ) works... yes checking whether the C compiler (gcc ) is a cross-compiler... no checking whether we are using GNU C... yes checking whether gcc accepts -g... yes checking whether gcc and cc understand -c and -o together... yes checking for PHP prefix... /usr/local checking for PHP includes... -I/usr/local/include/php -I/usr/local/include/php/main -I/usr/local/include/php/Zend -I/usr/local/include/php/TSRM checking for PHP extension directory... /usr/lib:/usr/local/lib/extensions/no-debug-non-zts-20020429 checking for GD support... yes, shared checking whether to enable truetype string function in GD... yes, shared checking for the location of libjpeg... yes, shared checking for jpeg_read_header in -ljpeg... yes checking for the location of libpng... yes, shared checking for png_write_image in -lpng... yes checking for the location of libXpm... yes, shared checking for XpmFreeXpmImage in -lXpm... yes checking for freetype(2)... yes, shared checking for FreeType 1.x support... yes, shared no - FreeType 2.x is to be used instead checking for T1lib support... yes, shared checking for T1_LoadFont in -lt1... no configure: error: Problem with libt1.(a|so). Please check config.log for more information. Before I'd compiled and installed libgd2.0.12 and I even tried different Versions of T1lib without any effect. I've tried it on SuSE 7.2, SuSE 8.1 and Debian 3.0r0. Would be great if anyone here could give me a hint. Regards Markus
