First, require is executed at run time, i.e. after the variables that
are presumably declared in config.pl have been used. Second, lexical
variables (i.e. 'my') are only visible in the scope in which they are
declared.

If you want to do it that way you will need to predeclare your global
variables with 'our' in BuildReport.pl before the require. Then,
assuming no package statements in BuildReport.pl, you could initialise
variables in config.pl like "$::var = ..." instead of "$var = ...".
However this is a pretty fragile solution. There are any number of
config modules on CPAN (e.g.
http://search.cpan.org/search?query=config&mode=all), many of which will
also be available via ppm. Picking one that matches your requirements
would probably be a better solution.
