64 bit linux

[Funog]

I am using SimplyMEPIS 6.5 64 bit linux. DMD used to work fine with previous 32 bit versions of SimplyMepis, but now linking would not work. A hello world ( void main(char[][] args){printf("Hello\r\n");}) gives :

funog at 1[ircw]$ dmd hello.d
gcc hello.o -o hello -m32 -lphobos -lpthread -lm -Xlinker -L/home/funog/dmd/bin/../lib
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.0.3/../../../libpthread.so when searching for -lpthread

/usr/bin/ld: cannot find -lpthread

I am not very good at linux... Is there a way to correct this problem, or will DMD just do not work on my distro?
