When emerging qtparted on a system using solely reiserfs the system downloads, among others, the userland tool packages for the ext2fs and jfs. However, jfs is merged before e2fs while it is dependent on a library called UUID, which is apparently part of the e2fsprogs package. Please fix internal dependency. nb: only people that do not use ext2 notice this problem, and there probably aren't many around.
Fixed - thanks for the report!
