I've installed the hack and it works fine.
The only potential problem that I can see is that if the user installs the counter on several pages, then they must ensure that Perl can get its hands on the 'DOCUMENT_URI' environment variable.
With my UBB, I can't actually see the contents of that variable, and thus, the Count.txt file always contains: |12345
Its no big deal for me since I currently only have the count hack applied to Ultimate.cgi, but I'd need to make alterations if applying it to other pages.
I guess you could use something else like 'REQUEST_URI' instead. I'll go give that a whirl and see what happens.
