See bug 1526, which said that resolver.3 was missing, even though it was referenced by several other manpages. 1526 says the problem was fixed at man-pages-1.24, but the file is missing in 1.26. Any place I could get a copy of the file in the meantime? 1.24 doesn't seem to be in any released distro: RH6.0 has man-pages-1.23, 6.1 has 1.26.

It seems fixed in rawhide (fixes might include updated less, gzip, man etc)
