[Users] P-D installation problem

Hello! So glad to join your community. We've desided to use our server like a sipproxy server, but I have a priblem during installation of OpenSER. It looks like there are some troubles with Makefile. I have Pentium-D 3200 Suse server and whenever I try to compile OpenSER I have the following message: linksysserver:/openser-1.0.1 # make all Compiling action.c gcc -g -O9 -funroll-loops -Wcast-align -Wall -minline-all-stringops -falign-loops -ftree-vectorize -mtune=x86_64 -DNAME='"openser"' -DVERSION='"1.0.1"' -DARCH='"x86_64"' -DOS='"linux"' -DCOMPILER='"gcc 4.1.0"' -D__CPU_x86_64 -D__OS_linux -DCFG_DIR='"/usr/local/etc/openser/"' -DPKG_MALLOC -DSHM_MEM -DSHM_MMAP -DDNS_IP_HACK -DUSE_IPV6 -DUSE_MCAST -DUSE_TCP -DDISABLE_NAGLE -DHAVE_RESOLV_RES -DF_MALLOC -DFAST_LOCK -DADAPTIVE_WAIT -DADAPTIVE_WAIT_LOOPS=1024 -DHAVE_GETHOSTBYNAME2 -DHAVE_UNION_SEMUN -DHAVE_SCHED_YIELD -DHAVE_MSG_NOSIGNAL -DHAVE_MSGHDR_MSG_CONTROL -DHAVE_ALLOCA_H -c action.c -o action.o action.c:1: error: bad value (x86_64) for -mtune= switch make: *** [action.o] Error 1 Do you have any ideas on how to solve this problem?
