Due to clash in name at bugzilla I changed ebuild name to
web.math.hr/~mdoko/gnu/moreutils-0.30-r2.ebuild

Here is ebuild that fixes man page generation problem:
web.math.hr/~mdoko/gnu/moreutils-0.30-r1.ebuild

0.30 - same thing.

Seems like 0.29 tarball lacks sponge.1, isutf8.1, ifdata.1, ifne.1, pee.1, mispipe.1, lckdo.1 man files, so emerge gives:

install sponge.1 vidir.1 vipe.1 isutf8.1 ts.1 combine.1 ifdata.1 ifne.1 pee.1 zrun.1 mispipe.1 lckdo.1 /var/tmp/paludis/sys-apps-moreutils-0.29/image//usr/share/man/man1

install: cannot stat `pee.1': No such file or directory

make: *** [install] Error 1

Please correct either ebuild itself, or tarball package
