After installing linkchecker (emerge linkchecker) I noticed that I could only read the man page if I was root. After investigating, I discovered that the permissions for /usr/share/man/man1/linkchecker.1.gz are 600, when they should be 644 like all the other man pages. This may be a bug with the linkchecker program as opposed to Gentoo, but I wasn't sure. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Fixed.
