I'm trying to install cffi package into sbcl. 
First, I tried clbuild that is recommended on the cffi installation page. 
When I tried to run :

```
clbuild quickload cffi

```

I was given an error saying :

```
The function ASDF::SOURCE-REGISTRY is undefined.

```

I then tried asdf-install, it end up complaining about 

```
Component "cffi-examples" not found

```

Any help on this would be appreciated.

**UPDATE**

For asdf-install, I'm running sbcl with slime. It seems that whenever it complains about a component that is missing, that component is actually installed. I just have to abort the debugger and restart Emacs, start slime, and do that install again, and it will finish successfully. If I don't run it with slime, just running it inside sbcl prompt in terminal, it will keep complaining about the component missing nonstop. 

So to get cffi installed with asdf-install, I had to restart Emacs for about 4-5 times.

I'm not sure if there is configuration issue with sbcl?

I suppose I should ask this question in different thread.
