Is there a way to set variables per package? I've a couple packages (db and pam) that simply do not like FEATURES=distcc, and I would like to disable it for those packages. Is there a way to do so?

yes, there is an way

you could set usefalgs dependend on this file for packages only , here is mine, have a look

Code:
notebook roman # cat /etc/portage/package.use     
#dev-libs/cyrus-sasl -gdbm berkdb
app-text/acroread nsplugin
#>=x11-base/xorg-sever-1.1.1-r1 minimal
sys-libs/ncurses minimal
x11-apps/xinit minimal
net-dns/openldap minimal
app-editors/nano minimal
dev-libs/libcdio minimal
sys-apps/miscfiles minimal
media-video/vcdimager minimal

#11.Dez.2006
app-cdr/cdrdao -gnome
net-misc/openvpn minimal
app-office/openoffice -gstreamer
notebook roman #

He didn't mean use flags, he meant portage variables. And as far as I know, you can't do that yet.

That doesn't work for FEATURES, does it?

Well, I suppose I COULD hack somethiong together using those handy variables below and a new file or three in /etc/portage and hide it neatly in /etc/portage/bashrc like I did my Dynamic DISTCC_HOSTS and MAKEOPTS generator. I was just hoping to avoid that. I'll wait before I start that.

declare -x FEATURES="autoconfig distlocks metadata-transfer parallel-fetch sandbox sfperms strict userfetch userpriv usersandbox"
declare -x EBUILD="/usr/portage/sys-libs/pam/pam-0.78-r3.ebuild"
declare -x PORTDIR="/usr/portage"
declare -x PORTDIR_OVERLAY="/home/portage/overlay"

I don't know if it will work for $FEATURES, but works good enough for $CFLAGS and $LDFLAGS:
make file eg. /etc/portage/env/media-sound/amarok for amarok and put in it your definition of variable: FEATURES="bleble". You could also try FEATURES="${FEATURES} -distcc" but I don't know how portage reacts for setting both distcc and -distcc (it should use the last one, I believe).

/etc/portage/env works for variables that are only used by the bash side of portage or the build system (like *FLAGS vars that portage itself doesn't care about). It may work for a few values of FEATURES (though for disabling you can't use the usual negation syntax), but generally it won't, same for most other variables usually found in make.conf as they are used before /etc/portage/env is parsed (which btw isn't done by portage itself).

Thanks for the info Genone - so I better return to /etc/portage/bashrc?

I had something previously working for that with the following:
Code:
# Workaround for creating different environments for specific packages
# For every package you need a separate file in /etc/portage/env.d !!!
# In this file you can specify the specific environment variables like
# FEATURES="-ccache"
#
# Thanks to Neil Bothwick <neil@digimed.co.uk> - 2006
for MY_ENV in ${PN} ${P} ${PF}; do
        if [ -f /etc/portage/env.d/${CATEGORY}/${MY_ENV} ]; then
                source /etc/portage/env.d/${CATEGORY}/${MY_ENV}
                fi
        done

but this does not work anymore and seems similar to /usr/portage/profiles/base/profile.bashrc :-/

Is there anything else I can do?

Same restrictions there. Anything with "bash" in the name can't influence the python side of portage.

Thanks again for the fast response Genone :)

This brings me back to the question: "Is there anything else I can do?"

Well, I know you can effectively do FEATURES=-distcc simply by setting your $DISTCC_HOSTS to localhost/2 and your MAKEOPTS to -j2 in /etc/portage/bashrc after you read in a file and see if you want to use avoid distcc with it. I have a good start on [/topic]something semi-related here.

I noticed that an export of the variable from /etc/portage/env/<cat>/<pkg> helps in some cases, like setting the $F77.
