ERROR: Cannot copy 'C:\Perl\html\Active.css' to '\Active.css': No such file or directory
That's a pretty odd sort of error to be getting - though it's similar to an error Windows users can experience with Inline-C-0.62 towards the the end of 'dmake test' when t/27inline_maker.t is run.
What version of Inline::C do you have ?
Can you provide a simple script that generates the above (or some similar) error.
