required use flags

[Alessandro-Barbieri]

I apologize for any mistake but I'm new to gentoo.

Trying to install sage and go this requests

The following keyword changes are necessary to proceed:
 (see "package.accept_keywords" in the portage(5) man page for more details)
# required by sci-mathematics/sage-6.6::sage-on-gentoo
# required by sage (argument)
=dev-lisp/ecls-15.3.7 ~x86
# required by sci-mathematics/sage-6.6::sage-on-gentoo
# required by sage (argument)
=sci-mathematics/pari-2.8_pre20150307-r1 ~x86

!!! The ebuild selected to satisfy "~media-gfx/tachyon-0.98.9[png]" has unmet requirements.
- media-gfx/tachyon-0.98.9-r2::sage-on-gentoo USE="png (selinux) -doc -examples -jpeg -mpi -opengl -threads"

  The following REQUIRED_USE flag constraints are unsatisfied:
    exactly-one-of ( opengl mpi )

(dependency required by "sci-mathematics/sage-6.6::sage-on-gentoo" [ebuild])
(dependency required by "sage" [argument])

[kiwifb]

tachyon has a complicated set of useflags so mistake are not surprising. I'll check that we have sensible default. Did you follow the instructions of the Readme at our github homepage, in particular section (3)? Your ecls requirement is strange unless 13.5.1 has been removed from the tree.

[Alessandro-Barbieri]

I linked the files as in Readme

If you have eix installed can you show me the output of eix ecls?

[kiwifb]

And while I am at it the full output of emerge --info sage

OK, I pushed something for ecls, now let's get to pari and tachyon useflags... Can you give me the output of eix sci-mathematics/pari and eix tachyon.

[kiwifb]

Pushed better useflags for tachyon by default.

You should synchronise the overlay and try again. It all look in order to me.

Seems working now.
