## If 'make' fails here, because it is linked with libffo.so.6
## (ldd /usr/bin/make|grep libffi) and you just
## removed it, you can do something like this in a pinch (maybe):
# cp -a x86_64-pc-linux-gnu/.libs/libffi.so.8.1.2 /usr/lib64/
# ln -s /usr/lib64/libffi.so.8.1.2 /usr/lib64/libffi.so.6
# ldconfig

# Install it
make install
ldconfig

# Become your non-root user again
exit

# Keep the source for later
cd
mkdir -p -m 0700 installed
rm -f installed/libffi-*.tar.*
mv libffi-3.4.4.tar.gz installed/

# If you ever want to uninstall libffi, this should do it:
