No such file or directory

[Slate]

When I open the BASH shell I get the 
following message.
 
warning: could not find /tmp, please 
create!
 
I then enter at the BASH 
prompt
 
mkdir -p /tmp
 
And get the following 
message...
 
No such file or directory
 
I get that same message when i try to 
create /bin.
 
Any suggestions?
