Asdf failed, Wheres the Error Description?

I get this error from time to time

It has always annoyed me, is there some way to get the actual error message? What does this error mean?

The error is usually somewhere earlier. It may help to try compiling the offending file by hand -- less messages to dig through.

Just wandering,would it be possible to change asdf to get the actual error message thrown by lisp instead of a general error?

Possibly, but then the set of restarts would probably be different (and less useful). Maybe the asdf error could contain the thrown error and have a restart to trigger the original error?

That would be awesome because it becomes tiresome when trying to compile and debug an external library using the 'asdf failed' error when all you want is for the darn thing to work
