in thread Loading a function from another file dynamically?!

thanks. that worked well :).. I think I'll just use number 3 since it's the shortest. eval() return values aren't that important to me, since it's only for my wwwsite. There aren't any real differences between these methods, are there?

The first method loads the file into a string, then evals it.

The second method uses an external program (cat) to read the file, taking up a bit more resources.

The third method is the "preferred" way of doing it, but has a couple of differences: the file is looked for in all the directories listed in the @INC array; the code in the file will not be able to access lexical variables declared (with my) in the scope in which the do is executed. (for details, perldoc -f do).
