sage-4.1.rc1 doesn't compile on 64-bit Gentoo linux:

This seems to be related to #6492. After using the 2.1.2.p1 spkg linked to from that ticket, ratpoints compiles. (4.1.rc1 is not yet done compiling, but it made it passed ratpoints.)

Replying to saliola:

This seems to be related to #6492. After using the 2.1.2.p1 spkg linked to from that ticket, ratpoints compiles. (4.1.rc1 is not yet done compiling, but it made it passed ratpoints.)

4.1.rc1 compiles fine with the proposed ratpoints package.

make ptest gave the following timeout errors:

----------------------------------------------------------------------

The following tests failed:

        sage -t  devel/sage/sage/schemes/plane_curves/projective_curve.py # 0 doctests failed
        sage -t  devel/sage/sage/rings/homset.py # 0 doctests failed
        sage -t  devel/sage/sage/rings/polynomial/multi_polynomial_ideal.py # 0 doctests failed
----------------------------------------------------------------------

I re-ran the tests several times and homset.py and projective_curve.py always passed. multi_polynomial_ideal.py, more often than not, just timed out.

Can these be related to ratpoints?

Since the other ticket provides a fix I am filing this as duplicate.
