In general, you should know that do* functions (helpers) set EPREFIX
behind the scenes.

There are two approaches here.
1) Have EPREFIX in GAMES_PREFIX (eclass) because it is used in ./configure
and makes sense to have it there. If you use "do* ${GAMES_PREFIX}/foo" then
you have to strip the leading EPREFIX out, such as "do*
${GAMES_PREFIX#${EPREFIX}}/foo"
2) Have GAMES_PREFIX not include EPREFIX and then add it to ./configure
--prefix="${EPREFIX}/${GAMES_PREFIX}"

Both approaches are in use and it depends on which way "makes the most
sense" (less diffs/less work) - I hope that sheds some light on the
subject.

soo... i dont see any problem with the install paths, no double prefix.
what is this error about using ${EPREFIX} with helpers?

before sending i googled and found this
http://www.mail-archive.com/gentoo-alt@lists.gentoo.org/msg03335.html

so it seems that the games eclass should not handle EPREFIX at all ?

but for confugure those do need to be set since that is whats passed,
econf --prefix="${GAMES_PREFIX}"

seems like doins needs to stop whinning ?

i think i am in favor of #2, but have the games.eclass use EPREFIX
internally where needed.


are there any other eclasses or parts of portage this is or was an issue ?
