[PLUG] Qpopper Problem

[josh]

I'm sure someone here has some experience with qpopper. I am trying to
install it on my RH7.2 system and when doing 'make install', I get teh
error: 

/usr/bin/install -c -m 0644 -o root ./man/popper.8 /usr/local/man/man8/
/usr/bin/install: cannot create regular file '/usr/local/man/man8/': is
a directory
make: *** [install] Error 1

Can anyone give me a clue how to fix it?

thanks,
josh
