AqBanking

When trying to update aqbanking for Arch Linux
the v6.5.0 build fails with the following error:

...
libtool: link: ( cd ".libs" && rm -f "libaqbanking.la" && ln -s "../libaqbanking.la" "libaqbanking.la" )

I am using the same PKGBUILD as for the previous version, with the update version number:
https://github.com/archlinux/svntogit-community/blob/packages/aqbanking/trunk/PKGBUILD

Cheers!
