Ty Tower,
I am sorry to say that I do not see how you could be progressing -slowly. 
You see I just looked through all of your other compile errors, and not 
one was having a problem finding -lm. This tells me that instead of 
progressing forward, your doing it backwards.

I do commend you for taking to the time to understand what the linker is 
doing and trying to figure out what you don't understand. (Your post was 
much more concise and polite in d.learn).

To recap:
[tytower at linuxbox import]$ dmd ./test_gridlayout.d
/usr/bin/../src/phobos/std/c/windows/windows.d(12): static assert  is
false

Conflicting tango and phobos, yes these end with cannot find -lXdamage, 
on problem can propagate another. (Life of a programmer)

Could not find reference to needed libraries, you used dmd instead of 
dsss or rebuild, so the proper -l flags were not added.

Exactly the same as the last one, no change in operation what-so-ever.



Now had -lm been missing everything would have stopped where you 
currently are stuck. So please don't claim BS, don't disregard are 
statements of improper versions. Surprisingly I'm still willing to help, 
but only if this ignorant bashing of help stops. You may not even want my 
help anymore, but I don't think anyone will be helping you if you 
continue with your current methods.
