File lnusertemp issue

[Temlakos]

Everyone:

Just did a clean install to Fedora 17 (x86_64 architecture) and KDE 4.

I used the Users and Groups app. (authenticating with the root password) 
to create two new users to hook in with two directories on /home (from 
the previous installation).

But when I try to log into either one, I get this:

call to lnusertemp failed (/Temporary directories full?)

But then when I try to execute lnusertemp manually, I can't find it. It 
seems never to have gotten installed.

What happened?
