There are three problems here:

1.) The error message is worded poorly.
2.) The error is actually referring to the .dll, not the .lib and
     is due to a bug with trailing slashes in the install destination.
3.) The .lib is mentioned even though it is not actually installed.

I've fixed #1 and #2 in CVS which should be enough to install Chicken 
properly.  Problem #3 will be fixed as part of more general changes I'm 
making.
