su -c "make install" gets gcc: error: /usr/lib/i386-linux-gnu/libsane.so: No such file or directory

Trying to install hplip on Ubuntu (Xubuntu) 12.04 used automatic installer. Failed on make step. Tried to manually run make install as per another entry I found on this list.

Is there anyway to fix this? Is it possible to just skip the Sane install and install it manually later?
