Re-compiling PHP

I am trying to re-compile php, but keep getting erros that the mysql extensions are not installed. I got the binary from php.net and included mysql in configure (following). What am I not doing correctly? ./configure '--prefix=/usr/local' '--enable-exif' '--enable-track-vars' '--with-calendar=shared' '--enable-magic-quotes' '--enable-trans-sid' '--enable-wddx' '--enable-ftp' '--with-gd' '--with-zlib' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr/local' '--with-ttf' '--with-openssl' '--with-gettext=/usr' '--with-gd' '--with-zlib-dir=/usr/local' '--with-png-dir=/usr' '--with-jpeg-dir=/usr/local' '--with-mysql' Thanks, -Mike
