Perhaps we can make a general fix, see below.

We've fixed this problem by building a temporary wget inside openssl 
compile It keeps wget working during openssl.  The other option, which 
is similar to yours, was to keep the old openssl binary around for a 
little bit until everything's recompiled to the new one.  

When Andrew and I discussed this issue before, I didn't really have 
anything fleshed out like your spell idea, but I'd still like to see it 
generalized.

I don't think we need to make it a special spell -- if we're going to 
fix it for this openssl issue, we could make sorcery smarter by keeping 
an index of what's linked to what (similar to what I pointed out in your 
blog) and have sorcery not dispel that libary until the index of what's 
linked to what sees that openssl 0.9.7 is no longer needed, and then, 
when it does see that it's no longer needed, have it automatically 
removed.

A kind of temporary alien store until the libraries are no longer 
useful.

We'd have to add "gaze visa" to gaze alien just so people can see what's 
lurking around.  cleanse --fix would then not just check against what 
links or doesn't link, it would check to see what links to a visa'd 
alien file and then rebuild it.
