Arch Linux

I've modified the PKGBUILD as follow and it worked:

# Maintainer : lembang <lembang@gmail.com>
# all credits goes to JabaDisa <admin@jabadisa.com>
# since i like to use xmind a lot, I noticed that this package is not always uptodate, just make it nicer
# to keep them always up to date

pkgname=xmind-gtk
name=xmind-linux
pkgver=3.5.1

pkgdesc="XMind is a powerful brainstorming and mind mapping software tool, based on the Eclipse platform."

package() {
# Extract DEB
cd ${srcdir}
tar -zxf ${srcdir}/data.tar.gz

# Relocate files
mkdir ${srcdir}/opt/xmind -p
mv ${srcdir}/usr/bin/XMind ${srcdir}/opt/xmind
cp -r ${srcdir}/usr ${pkgdir}/
cp -r ${srcdir}/opt ${pkgdir}/

# Correct paths in .desktop file
sed -i 's/\/usr\/local\/xmind/\/opt\/xmind/g' ${pkgdir}/usr/share/applications/xmind.desktop

# Symlink binary to /usr/bin
mkdir ${pkgdir}/usr/bin -p
ln -s /opt/xmind/XMind ${pkgdir}/usr/bin/xmind
}

3.5.x is out now:
