graphics/jpeg build failure - libtool not found?

[Iain Hibbert <plunky%rya-online.net@localhost>]

Hi,
   I'm in the process of updating my several months old system, I've build
a new NetBSD-current release and installed a new kernel. I've not
installed the userland all over yet, but am using the new release with
pkgtools/pkg_comp to build packages in a sandbox.

   I am getting the following error when trying to build graphics/jpeg:

Any ideas what might be going wrong?  libtool is installed but there is no
libtool in the jpeg-6b directory, maybe because ltconfig failed?
