This is the exact problem I reported a few months ago at 
http://savannah.nongnu.org/bugs/?func=detailitem&item_id=13416

The workaround given in the bug report is to temporarily rename the 
various autoconf files in /usr/bin. E.g.
# mv autoconf autoconf.original
# mv autoconf-2.13 autoconf

Without renaming the files as described above, autoconf --version will 
actually run /usr/lib/misc/ac-wrapper.sh, which will then execute 
autoconf-2.13 --version.
