I know little of such things, but you must be right, I guess. Note
that iconv is only disabled for 64-bit builds:
if [ "$SAGE64" = "yes" ]; then
echo "Disabling iconv on 64 bit OSX"
OSXFW="--enable-R-framework=no --with-iconv=no"; export OSXFW
The history of this disabling is at
http://trac.sagemath.org/sage_trac/ticket/3196.
Interesting that no one has reported problems with the updated R spkg
on 64-bit OSX, that I can remember, but apparently you are right that
this flag is simply now ignored *and* that there must now be 64-bit
libiconv support (whatever that is).
