smc-get build fails for worlds

[Quintus]

The interactive build process fails if worlds are included:

Welcome to the smc-get build process! 
Answer the following questions properly and you'll end up with a ready-to-
install package you can either install locally or contribute to the repository
(which would make it installable via 'smc-get install' directly). When a question
asks you to input multiple files, you can end the query with an empty line.
If you like, you can specify multiple files at once by separating them
with a comma. Wildcards in filenames are allowed.

Files you don't specify via an absolute path (i.e. a path beginning with
either / on *nix or <letter>:\ on Windows) are searched for in your
home directory's .smc directory and your SMC installation.

Enter the names of the levels you want to include:

This is because it tries to treat the world directory as a file when it tries to copy it to the temporary directory for compressing.

The world I tried to package is the one from this thread: http://www.secretmaryo.org/phpBB3/viewtopic.php?f=21&t=4608

How hard would this be to fix? Is there a good function to copy entire directories or will we have to write our own recursive function?

[Quintus]

No need to reinvent the wheel. I already use the FileUtils module (stdlib) excessively in smc-get and it provides the cp_r method that does a quite good job on copying directories recursively.
