srfi-88 module is broken somehow

[sjamaan]

The following program refuses to run or compile:

(import srfi-88)
;(import (chicken keyword)) ;; this works

(print (string->keyword "foo"))

[sjamaan]

NOTE: This affects the "edn" egg. Strangely enough, it only seems to affect its test suite... The code itself also uses string->keyword.

Should be fixed with 111a5a24
