Compiling this gives the following output -- oh, and BTW, there's no 
/home/clark on my machine. :-)


$dmd st2.d
gcc st2.o -o st2 -lphobos -lpthread -lm

Changing "std.process" to "std.c.process" works. For example:


import std.c.stdio;
import std.c.process; // Skip the ".c" and it breaks.

int main(char[][] args)
{
     printf("Trying the 'system(cmd)' thing.\n");
     char[] cmd = "/bin/ls -l /root /home >/tmp/ls.out 2>/tmp/ls.err ";
     int err = system(cmd);
     printf("system(cmd) returned %d.\n", err);

     return err;
}
