If you try to build a standalone application which uses Crane you will probably run into problems when the compiler tries to dump the lisp image. It will complain about open database connections.

Writing code portably is useful for easily switching between Common Lisp implementations and for building cross-platform applications. I place a lot of emphasis on portable code in my upcoming book. During my research, after a prompt from @fare, I discovered that UIOP provides some useful portability functions beyond file access.
When you decide to make an application standalone using the two step process it is possible that you may encounter the following situation: the build process completes without a problem but running the program lands you in the debugger with a message about Quicklisp not being found.
