- sci-mathematics/sage-7.2::sage-on-gentoo USE="X bin-html pdf -bin-pdf -bliss -debug -html -latex -modular_decomposition -sagenb -testsuite" ABI_X86="64" LINGUAS="en fr ru -ca -de -hu -it -ja -pt -tr" PYTHON_TARGETS="python2_7"

  The following REQUIRED_USE flag constraints are unsatisfied:
    bin-html? ( !pdf )

  The above constraints are a subset of the following complete expression:
    html? ( linguas_en ) testsuite? ( any-of ( bin-html html ) ) bin-html? ( !html !pdf linguas_en ) bin-pdf? ( !html !pdf linguas_en ) any-of ( python_targets_python2_7 )

This is the first time I'm installing Sage. I'm not sure what extra information I can provide to help debugging this.

No extra info needed. You should also use package.use/99sage-bin-doc to have sane flags for the documentation. There is a small note about it in the README but it should be updated.

Thank you, it worked. (although I'm not actually an ~arch user)

[kiwifb]

If you think it is for ~arch user the README definitely needs rewriting.

[dniku]

I have some packages ~amd64 unmasked, but I'm mostly using stable versions. And I'm not sure if I understand correctly what you mean.

[kiwifb]

I pointed you to use package.use/99sage-bin-doc and you answered

Thank you, it worked.

So if you think that this file is for ~arch users, I have some writing to do.

[dniku]

I said this because the README says:

This is recommended for ~arch users.

[kiwifb]

Right. It really need updating.
