about php modules

Hi, I have a query regarding xsl, gd and curl rpms for php. I am not able to find them on http://mirror.karneval.cz/pub/linux/fedora/linux/releases/13/Fedora/i386/os/Packages/ Can you please let me know where can I find rpm's for these modules? I also downloaded php-5.3.3 and compiled it with : ./configure --with-xsl --with-gd --with-curl and after "make install" found that xsl.so, gd.so, curl.so under /usr/local/lib/php/extensions/no-debug-non-zts-20090626/ So, just want to know if these .so files are the same ones which are provided by php-xsl, php-gd, php-curl rpm's? or do these rpm's provide anything more than these .so files?
