Bug#493702: tla(GNU/k*BSD): FTBFS: out of date libtool scripts
the current version fails to build on GNU/kFreeBSD,
because of outdated libtool.
The version of libtool in src/expat is too old to correctly
support Debian GNU/k*BSD, libtool 1.5.2-1 or later is need.
Here is how to update the libtool in your package:
cp /usr/share/libtool/ltmain.sh conftools/
cp /usr/share/libtool/libtool.m4 conftools/
Thanks in advance
