You're getting this bug because the package in summary installs its
documentation (or at least part of it) outside the usual /usr/share/doc/${PF}
directory.
First, please keep in mind that this bug might not be noticeable for -r0
ebuilds, but it might be for -r1 and later, since if the ebuild has same name
and version of the package, for -r0 it might correspond properly.
To fix this, if the package uses autotools, recent version (autoconf 2.61+)
have two ./configure switches: --docdir and --htmldir to decide where to put
the documentation. Older versions might require you override docdir/htmldir or
other custom variables during make install.
For non-autotooled build systems, good luck, since I cannot tell you how to
achieve the proper results, the same holds true with totally broken
buildsystems even when based on autotools.
Thanks,
Diego
