du depends heavily on stat - which is POSIX. So writing C code is failry portable,
along with the dirent.h functions
perl implements stat, so that's cake. The other needed calls: closedir, opendir, and readdir to get file names to stat. Both of those are in perl as well.... go for it.
Perl by Example has an example getting all the file names in a directory.
This does something else with stat data as entry-level example code for the forums here, but you can clean it up for your use:
