I am having a problem compiling a simple program when working through "The D
Programming Language". The program is like so:

#!/usr/bin/rdmd

import std.stdio, std.string;

void main()
{
  //Compute counts
  uint[string] freqs;
  foreach(line; stdin.byLine())
  {
    foreach(word; split(strip(line)))
    {
      ++freqs[word.idup];
    }
  }

  //Prints count
  foreach(key, value; freqs)
  {
    writefln("%6u\t%s", value, key);
  }
}

but this is the error I get when running it.

brian brians-tower:~/Programming/D$ ./readingHamlet.d
object.d: Error: module object is in file 'object.d' which cannot be read
import path[0] = .
Failed: dmd  -v -o- './readingHamlet.d' -I'.' >./readingHamlet.d.deps

I feel its probably something to do with the way I have installed/compiled the
library but I'm at the end of my current knowledge in how to fix this. Any
idea on where I should be looking/what I should be looking for? I have been
following the various advices on how to install the library correctly, but
feel I may have gotten myself into more trouble doing this now.

Regards
Brian

It means that it can't find the source code for druntime. Likely, your dmd.conf 
is messed up or it's in the wrong place. There should be a dmd.conf file next 
to the dmd binary. It defaults to something like this

[Environment]

DFLAGS=-I% P%/../../src/phobos -I% P%/../../src/druntime/import -L-
L% P%/../lib64 -L-L% P%/../lib32 -L--no-warn-search-mismatch -L--export-
dynamic -L-lrt

Assuming that you just unzipped the zip file and used that, then everything 
should be in the right place. Presumably, the same goes for the deb or rpm 
packages if you used those. If you moved any of it around yourself, then 
you're probably going to have to make sure that you have dmd.conf next to the 
dmd binary and that it actually sets DFLAGS such that it points to where the 
source for druntime and Phobos is as well as where libphobos.a is.

Ah yes, that makes sense. I just needed to change the
#!/usr/bin/rdmd
to where my library was ie.
#!/home/brian/dmd2/linux/bin64/dmd
which, now that I look at it, makes a lot more sense!
Different errors now \o/

Thank you.

The error message could be a lot better. I've posted a bug report with 
suggested wording:
