Bugzilla Bug 149857

I installed man-db because man doesn't support unicode, but emerge wants to
install man again:

# emerge -uDptv world

These are the packages that would be merged, in reverse order:

Calculating world dependencies... done!
[blocks B     ] sys-apps/man-db (is blocking sys-apps/man-1.6d)
[nomerge      ] media-gfx/gwenview-1.3.1-r1  USE="arts -debug

[ebuild  N    ]        sys-apps/man-1.6d  USE="nls" 0 kB

I think that some ebuild should require virtual/man (provided by both) instead
of sys-apps/man.

In /usr/portage/eclass/x-modular.eclass there is: 

RDEPEND="${RDEPEND}
        >=sys-apps/man-1.6b-r2
        !<=x11-base/xorg-x11-6.9"


I've changed it with:

RDEPEND="${RDEPEND}
        virtual/man
        !<=x11-base/xorg-x11-6.9"

Now man is not required but I don't know if this change breaks something.

That man dep is so that it looks in extra sections for X man pages --
/usr/share/man/man[0-9]x. Does the same thing need to get added to man-db?

Do you mean this:

$ man radeon
No manual entry for radeon

$ man 4x radeon
Reformatting radeon(4x), please wait...

?

Yes.

Incidently (and, yes, based on the original subject :) :

    app-doc/daemontools-man-20020131
    app-doc/djbdns-man-20020130
    app-doc/djbdns-man-20031023
    app-i18n/man-pages-de-0.4

all RDEPEND on "sys-apps/man".

In /etc/man_db.conf there is:

# Section names. Manual sections will be searched in the order listed here;
# the default is 1, n, l, 8, 3, 2, 5, 4, 9, 6, 7. Multiple SECTION
# directives may be given for clarity, and will be concatenated together in
# the expected way.
# If a particular extension is not in this list (say, 1mh), it will be
# displayed with the rest of the section it belongs to. The effect of this
# is that you only need to explicitly list extensions if you want to force a
# particular order. Sections with extensions should usually be adjacent to
# their main section (e.g. "1 1mh 8 ...").
SECTION         1 n l 8 3 2 5 4 9 6 7

I've added "4x" to the list and now man works also with extra section for X:

$ man radeon
Reformatting radeon(4x), please wait...

man-db-2.4.3-r1 now supports the x categories

Fixed in CVS, thanks!
