Here's my recipe (for SageMathCloud) for building 4ti2:
# 4ti2 into sage: until the optional spkg gets fixed:
./sage -sh
cd /tmp; wget http://www.4ti2.de/version_1.6/4ti2-1.6.tar.gz &&
tar xf 4ti2-1.6.tar.gz && cd 4ti2-1.6 ; ./configure
--prefix=/usr/local/sage/current/local/; time make -j16
make install # this *must* be a separate step!!
rm -rf /tmp/4ti2*
