By the way, that failure is only in the config stuff.
I didn't carefully scrutinize that part of the patch
the Ubuntu folks gave me.  Looks like guile 1.6 doesn't
support scm_c_make_string and 1.9 has no alternative.
Thus, the config test code needs some if-def-ing.
Perhaps the Guile folks can point me to some config
test code that will identify a working Guile of the
1.4.x through 1.9.x persuasion.  It is getting very
difficult.

P.S. note to Guile folks:  I set this in my testing environment:

and had never been whacked with any deprecated messages
until Ubuntu could not build because deprecated interfaces
were dropped.  I think this was because the deprecated
interfaces were #define-d to non-deprecated interfaces and
the libguile couldn't tell that I was using old stuff.
May I suggest *NOT* eliminating such interfaces until
they've been #define-d to something that *DOES* warn?

e.g.
  #define SCM_NFALSEP(_a) scm_is_true_deprecated(_a)
