My RDF::Query module (available on CPAN[1]) supports SPARQL queries  
over models provided by RDF::Core, RDF::Redland, and RDF::Trine. The  
installation should be straightforward but there are some dependencies  
that might be tricky to install if you can't compile native code.

RDF::Query can use SQLite or non-relational data stores including in- 
memory and BerkeleyDB. Any of these could pull from a flat file each  
time your program runs, but performance might be an issue depending on  
your data and use cases.
