Condition of type: SIMPLE-ERROR

Package ((SB-BSD-SOCKETS . #<SB-BSD-SOCKETS package>)) referenced in compiled file

  NIL

but has not been created

Available restarts:

1. (IGNORE) Ignore the error, and try the operation again

This error is similar to cffi and uiop problem, I wrote recently (https://mailman.common-lisp.net/pipermail/ecl-devel/2016-June/011119.html).

But a trick with making package immutable, like this (asdf:register-immutable-system "SB-BSD-SOCKETS") does not work now.

Tested on Ubuntu ECL 16.1.4 and OSX 16.1.2.

Full example is available in https://github.com/svetlyak40wt/test-ecl in branch try-web-app. To build a binary, you need to issue ./bootstrap && ./build commands, and after them, run ./test-ecl.

Why do I have this problem and how to fix it?
