Using schemepunk with CHICKEN Scheme also depends on srfi 111

[tkurtbond]

When I try to compile schemepunk using CHICKEN Scheme I get the following compilation error:

building schemepunk
   /usr/local/sw/versions/chicken/5.3.0/bin/csc -host -D compiling-extension -J -s -regenerate-import-libraries -setup-mode -I /usr/local/sw/src/scheme/chicken/eggs/schemepunk -C -I/usr/local/sw/src/scheme/chicken/eggs/schemepunk -R r7rs -X r7rs -debug-level 2 box.sld -o /usr/local/sw/src/scheme/chicken/eggs/schemepunk/schemepunk.box.so

Syntax error (import): cannot import from undefined module

        srfi-111

A chicken-install srfi-111 fixes the problem.
