Compiled program complaints on absent UIOP/OS and UIOP/PATHNAME

Hi!

I have created a command line program: https://github.com/svetlyak40wt/cl-jslog

I've tried to build it with sbcl and it worked fine. But when I compiled it with ECL, I found that right after running, it outputs following error:

Condition of type: SIMPLE-ERROR The packages ((UIOP/OS . #<UIOP/OS package>) (UIOP/PATHNAME . #<UIOP/PATHNAME package>)) were referenced in compiled file NIL but have not been created Available restarts:

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

Top level in: #<process TOP-LEVEL>.

Tried ECL 16.1.4 on Ubuntu and ECL 16.0.0 on OSX.

What is the reason of this error, and how to fix it?
