The pre-build does not fix the problem with the DBD:Mysql.

However just as I was about to throw the machine out in to the rain I was able to get DBI to work. ( At least at first glance. )

In my MySQL libs I had three instances of libmysqlclient.

libmysqlclient.so.15.0.0
libmysqlclient.so.15
libmysqlclient.so

.so.15 and .so were links to libmysqlclient.so.15.0.0 so I removed them.

I then ran make again on DBD-mysql-4.005 and then make install.

I then ran the test.pl which seemed to work as it gave me a good error : )

DBI connect('database=test;host=localhost','joe',...) failed: Access denied for user 'joe'@'localhost' (using password: YES) at test.pl line 7

I will run more tests today and then report back if there are any other problems.
