Got the following error while trying to emerge samba into my Gentoo box.

I'm still searching for a solution to this issue. I've heard it has to do with trying to use the kerberos USE flag (which is not an optional flag for me). The closest possible solution in Google is on the Gentoo forums (Problems upgrading to Samba 3.0.14a-r2!). The user, "jpnag", posts a solution.

The solution involves editing the ebuild file for Samba. This is where you will need to become a bit more knowledgeable about how portage and emerge works (see "man make.conf" for details on some of this along with "man portage").

By default, portage downloads and installs packages under the "/usr/portage/" tree (defined by "PORTDIR=" in your "/etc/make.conf" file or "/etc/make.profile/make.defaults" file). There is also an optional define, "PORTDIR_OVERLAY=", which you can use to point at a tree containing user-built ebuild files that are not updated by "emerge --sync". Essentially, the second tree will overlay the first. So if you have "package X" in both trees, only the one in the overlay tree will get compiled.

Now to create the backup copy of the broken Samba ebuild. If you have not already added "PORTDIR_OVERLAY=" to your "make.conf" file, you should also do this.

# cd /etc
etc # echo 'PORTDIR_OVERLAY="/usr/local/portage"' >> /etc/make.conf
etc # cd /usr/local
local # ls /usr/portage/net-fs/samba/
local # mkdir portage ; cd portage
portage # mkdir net-fs ; cd net-fs
net-fs # mkdir samba ; cd samba
samba # cp -a /usr/portage/net-fs/samba/* .
samba # ls -l samba-3.0.14a-r2.ebuild
samba # nano -w samba-3.0.14a-r2.ebuild

Now hit [Ctrl-W] and type "src_compile", which will take you straight to the following code block:

rc_compile() {
        ebegin "Running autoconf"
                autoconf
        eend $?

        local myconf
        local mymods
        local mylangs

        if use xml || use xml2 ;
        then   
                mymods="xml,${mymods}"
        fi

Somewhere towards the start of the funciton, add the line "addpredict /etc/krb5.conf".

src_compile() {
        ebegin "Running autoconf"
                autoconf
        eend $?

        local myconf
        local mymods
        local mylangs

        addpredict /etc/krb5.conf

        if use xml || use xml2 ;
        then
                mymods="xml,${mymods}"
        fi

Create the ebuild digest (MD5 signatures) for the patched package.
