Asterisk on Suse 10.2, 64 bit

I was having problems compiling Zaptel and Asterisk-1.4.4 on a Suse 10.2 Linux system. There are files that I need but can’t find them. They are
libssl-dev
libnewt-dev
zlib1g-dev
initrd-tools

I have an Intel Pentium D 935 processor which is a 64 bit CPU. Do I have a CPU problem in that the missing files are not available yet for this CPU. Help Any ideas?
