This was built using Gitian with sipa's build script
Can you provide more details? I tryed to compile on a VMWare Ubuntu myself, but got errors 
1. install: https://github.com/devrandom/gitian-builder (install dependencies, then "git clone git://github.com/devrandom/gitian-builder.git")
2. git clone git://ShadowOfHarbringer/bitcoin-nftf/
3. rename folder "bitcoin-nftf" to "bitcoin-build"
4. follow the instructions to set up the gitian virtual machine
5. place dependencies in the input folder of gitian
5. ./bitcoin-build.sh nftf-v0.8.1
