Checking for URI.............. ok Checking for DBI.............. missing - You need the DBI module to run RDQL/Squish queries; without it only API based triple-match will be possible Checking for XML::Parser...... ok WARNING: 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 (use --disable-rule=EXPAT while building your apache-1.3.xx + mod_perl) Sorry, can not build RDFStore :( Please installed the missing modules above and try again. make: *** No targets specified and no makefile found. Stop.
