Corrections for: http://www.digitalmars.com/d/2.0/dmd-osx.html
1) it still refers to the dmd directory, but all directory references should be dmd2
2) there is no "rdmd", so this line:
   chmod u+x dmd/osx/bin/{dmd,dumpobj,obj2asm,rdmd}
should probably be:
   chmod u+x dmd2/osx/bin/{dmd,dumpobj,obj2asm}
3) probably have to use "sudo":
   cp dmd/osx/bin/dmd.conf /etc
should probably be:
   sudo cp dmd2/osx/bin/dmd.conf /etc
4) probably have to use "sudo":
   cp dmd/osx/lib/libphobos2.a /usr/lib
should probably be:
   sudo cp dmd2/osx/lib/libphobos2.a /usr/lib
5) Cannot find "shell" or "shell.exe" for osx, so this line:
   /dmd/bin/shell all.sh
is probably not applicable to osx, or if it is, then all.sh needs to be changed.
