You have installed a recent version of the XML::Parser (>2.29) with built in expat XML parser support. If you are going to use RDFStore inside the Apache Web server using mod_perl, bear in mind that there is a symbol conflict between XML::Parser and apache when built with expat. To properly use the RDFStore parsing modules you need to rebuilt apache disabling expat.

You do not have local database storage module installed. RDFStore will not able to store any kind of results on the local file system; the in-memory syle will be used instead. If you can get the DBMS module below installed you can leverage on a remote storage.

};

print <<EOT;

In addition, you can install the (optional) DBMS module for TCP/IP remote storage by:

cd dbms;
make;
make install;

NOTE: the dbmsd(8) code uses old Berkeley DB 1.x style interface. If you can not get it compile, do not disperate and try to use perl land BerkleyDB, DB_File or SDBM_File styles instead :-)
