Guile 2.0.6

Howdy g-wrappers,

G-wrap doesn't like the new Guile 2.0.6 as scm_sym2var and
scm_module_lookup_closure are now deprecated.  And since the default
is to compile with -Werror, that ends in a failed build.  Configuring
with --disable-Werror seems to work fine.

Here is an attempt to use a the newer non-deprecated replacements.
