All the commands of icicles seems to be not defined (i.e. when I hit 
'M-x icicles' and them 'Tab', the auto-completion says that there is no 
match). It seems that those commands are not built-in in my emacs. I'm 
using GNU Emacs 24.0.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 
2.20.1). How can I download and install these commands or enable them 
while compiling? I compiled it by myself, so it is possible that I 
didn't selected the correct options while compiling.

Thanks for your attention
