This turns out to be the same problem I have been facing and have still not solved. My thread on this question can be seen here:
Perl XAMPP DB Connect issue (Windows/Strawberry?).
I will be watching this thread now to see if any solution appears. The path fixes do not seem sufficient to solve it--there are missing files in the installation, such as "mysqlclient.lib" and a host of extras which must be installed just to try to compile the Makefile.PL.
