/usr hierarchy repeated in RPM

I am trying to install an RPM converted from a .deb with Alien. At the top of the file list I see with "less," the RPM wants to create /usr, /usr/bin, etc again. This gives me the following error message in an Xterm:
I thought that the obvious thing to do would be to leave out the creation of the filesystem but pcal is structured in the same way. pcal is an old Mandriva RPM. The developer knows nothing about RPMs, and I seem to be the only one with this problem (what's new?)
Is it perhaps due to Mageia advancing to RPM 4 ?
