FEMLISP can link to two sparse direct solvers, namely SuperLU or UMFPACK. Again those solvers have to be supplied as shared libraries. On Debian/GNU Linux, these are available as packages called something like “libsuperlu<version>” or “libumfpack<version>”.

Note that direct solvers are not necessary for most of the FEMLISP demonstrations, because hierarchical solvers are usually more efficient.
