There are two problems
Then it does some stuff (Creating DBI::PurePerl.....) and gives me the following error: "Warning: Prerequisite Test::More failed to load: Can't locate......."
This clearly means you need to find the Test::More module and install it (I'm sure it's at CPAN althought I haven't looked). That should allow everthing to work. However there is a Warning that I don't know how to advise you:
When I run perl makefile.pl, I get the following warning: "You are using a perl configured with threading enabled. You should be aware that using multiple threads is not recommended for production environments"
Obviously you could have performance issues if you use this install of perl. A quick google for "perl threading enabled DBI" turned up a lot of links. The only useful one was this quote from http://www.hk8.org/old_web/linux/dbi/appa_08.htm
If the DBI is built using a Perl that has threads enabled, then it will use a per-driver mutex to ensure that only one thread is with a driver at any one time. Please note that support for threads in Perl is still experimental and is known to have some significant problems. Its use is not recommended.
