Fish Exception (gh_standard_handler dump):
tag        :
throw args :
data       : [/usr/share/fish/extensions/utils.scm]
misc-error(#f %s %S (no such module (srfi srfi-13)) #f)No backtrace available.

/usr/share/fish/extensions/utils.scm contains:
(use-modules (srfi srfi-13))

i greped SPECS and found scsh contains it, but how after install it still 
can't find the srfi-13 module

(and i'm really dumb on schema language)
