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?

Regards,
Girish
