It would be helpful if you confimed what the linkages for gtar looked like 
with...

otool -L /usr/local/Cellar/gnu-tar/1.29/bin/gtar

and double check that you don't have any headers or libs for libiconv, gettext, 
and libintl
accidentally installed in /usr/local (to make sure you aren't ending up with 
mismatched headers
and libs during the tar build).

ps I suspect you will also find that passing --disable-nls to configure during 
the tar build will
also suppress your problem. Also, I suspect that building tar against libiconv 
without gettext
is poorly tested on OS X. Both fink and Macports build their tar packages with 
their gettext and
libiconv packages installed. Homebrew seems to be an outlier (and oddly 
non-deterministic) as
it doesn't bother to depend on either.
