I made the mistake of assuming that gcc was automatically 
installed in MAC OSX. After installing Xcode the problem went 
away. To answer your questions though:

I'm using DMD version 2.058 for MAC OSX which I installed using 
the .dmg package available at 
"http://www.dlang.org/download.html".

"gcc --version" yields:

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. 
build 5658) (LLVM build 2336.9.00)

"uname -a" yields:

Darwin Andrews-MacBook-Pro.local 11.3.0 Darwin Kernel Version 
11.3.0: Thu Jan 12 18:47:41 PST 2012; 
root:xnu-1699.24.23~1/RELEASE_X86_64 x86_64

the average program is as follows:

[code]
import std.stdio: stdin, writefln;
import std.conv: to;

void main(string[] args)
{
    double sum = 0.0;
    int cnt = 0;
    foreach(line; stdin.byLine())
    {
       if(line.length)
       {
          sum += to!double (line);
          cnt++;
       }
    }

    double avg = sum / cnt;
    writefln("Average is %.5f", avg);
}
[/code]

and I doubt you want me to put all of what "dmd -v" spits out for 
this little script.

Thanks,
Andrew
