compile php with GD2

hi there, i tried to compile php with GD2 support and the following configure line: ./configure --with-apxs=/usr/local/apache/bin/apxs --with-xml --with-curl --with-swf=/usr/local/flash --enable-ftp --with-gd=/usr/lib --with-jpeg-dir=/usr/local --with-xpm-dir=/usr/X11R6 --with-png-dir=/usr --with-imap --with-ming --enable-magic-quotes --with-mysql --enable-safe-mode --enable-track-vars --with-ttf --enable-versioning --with-zlib ...but i allways get the following error: checking whether to include include FreeType 1.x support... yes checking whether to include T1lib support... no configure: error: Unable to find libgd.(a|so) anywhere under yes Problem is, that the libgd.a file IS located in /usr/lib, as set in --with-gd, but it doesnt matter how i edit the line, i allways get this error. Does anyone have an idea, what i could try to get it compiled? Regards, Duncan
