DOS\>exerb watch1.rb

and the output is watch1.exe

DOS\>watch1.exe

C:\ruby\samples\FileSystemWatcher\>watch1.exe  
./filesystemwatcher.rb:1:in `require’: No such file to load – md5  
(LoadError)  
from ./filesystemwatcher.rb:1  
from watch1.rb:4

Why exerb does not build require libs to .exe ??

any help would be greatly appreciated much.  
Thanks a lot.
