CVS build fails

I'm trying to compile from CVS and have been receiving errors on a consistent basis. Sometimes I can track down the problem and sometimes I cannot. This is one of those times when I cannot. The build fails at:

I've been trying to build on Archlinux using an inherented PKGBUILD which is as follows:

# Contributor: Aaron Schaefer <email address hidden>
arch=(i686 x86_64)
pkgname=inkscape-svn
pkgver=18722
pkgrel=1
pkgdesc="A vector-based graphics editor that uses the SVG file format"
url="http://inkscape.sourceforge.net/"
license=('GPL2')
depends=('gtkmm' 'libart-lgpl' 'popt' 'gc' 'desktop-file-utils' 'gtkspell' \
 'libxslt' 'perl' 'python' 'libgnomeprintui' 'loudmouth' 'lcms' 'boost')
makedepends=('intltool' 'pkgconfig' 'subversion' 'versionpkg' 'gsl' 'boost-build')
provides=('inkscape')
conflicts=('inkscape' 'inkscape-nognome')
install=('inkscape-svn.install')

md5sums=()

_svntrunk=https://inkscape.svn.sourceforge.net/svnroot/inkscape/inkscape/trunk
_svnmod=inkscape

build() {
  cd $startdir/src

  msg "Connecting to svn.sourceforge.net SVN server..."
  svn co $_svntrunk --config-dir ./ -r $pkgver $_svnmod
  cd $_svnmod

  msg "SVN checkout done or server timeout"
  msg "Starting make..."

  ./autogen.sh

  mkdir -p ../$_svnmod-build
  cd ../$_svnmod-build

  ../$_svnmod/configure --prefix=/usr \
    --enable-inkboard \
    --enable-lcms \
    --disable-mmx \
    --with-xft \
    --with-python \
    --with-perl \
    --without-gnome-vfs
  make || return 1
  make DESTDIR=$startdir/pkg install

  rm -r $startdir/src/$_svnmod-build
}

The last few times I've tried to makepkg using this the build fails, but I have successfully used it in the past. Can someone point me in the right direction as to why this is failing to compile correctly? I'm planning on a complete re-write of the PKGBUILD eventually to conform to the Archlinux standards but seem to run into SVN build failures on a regular basis, so I don't want to waste my time if compilation is going to consistently fail.
