Unbound variable: quote

Unbound variable: quote

Hello,

I'm trying to load a file at the REPL that loads some modules from a
subdirectory then defines a function.  At reading my use-modules
statements, I get the following error:

guile> %load-path
("/home/joel/Public/src/age_dep/sim/trunk" "/usr/share/guile/site" "/usr/share/guile/1.8" "/usr/share/guile")
guile> (load "age_dep.scm")

Backtrace:
In unknown file:
    ...
   ?: 20  (letrec ((load-file #)) (dynamic-wind (lambda () #) (lambda () #) ...) ...)

   ?: 39* (quote (ice-9 popen))

<unnamed port>: In expression (quote (ice-9 popen)):
<unnamed port>: Unbound variable: quote
ABORT: (unbound-variable)

However, at the REPL I can load the popen module just fine (with a
warning):

guile> (use-modules (ice-9 popen))
guile> (use-modules (age-dep-scm age-dep-interface))
WARNING: (guile-user): `quote' imported from both (ice-9 null) and (age-dep-scm age-dep-interface)

Why would `quote' be redefined?  What's going on here and how can I fix it?

Thanks,

Joel

Perhaps the module that you are calling use-modules in has no binding
for `quote'.

This problem is fixed in 1.9, FWIW.

Is there anything I can do about that?  Would I have to redefine quote
in my top-level script?

Thanks for letting me know: unfortunately despite its reputation Fedora
is not quite "bleeding edge" enough for me ;)

No, this usually happens because you make a #:pure module, while not
defining imported modules within the define-module #:use-module clauses,
instead using the use-modules toplevel syntax.

Hope that helps,
