The package "solve_rat_ineq" not work on Maxima v5.21.0.
(%i1) load("solve_rat_ineq");
(%o1) "C:/Programmi/Maxima-5.21.0/share/maxima/5.21.0/share/contrib/solve_rat_ineq.mac"

(%i2) solve_rat_ineq(x-1>=0);
(%o2) []

(%i3) solve_rat_ineq(x-1>=0);
(%o3) all

It worked on maxima v 5.20.1.

Idem for other package of other contributor about inequalities (interval_arithmetic, ineq_domain).
For it see http://www.math.utexas.edu/pipermail/maxima/2009/019625.html
I think that it is the same problem.

Sorry for my bad english.

    I think that the problem is in realnonly which is set to true in the package.

    Maxima version: 5.21.1
    Maxima build date: 8:13 4/26/2010
    Host type: i686-pc-mingw32
    Lisp implementation type: GNU Common Lisp (GCL)
    Lisp implementation version: GCL 2.6.8

    display2d:false;

    algsys([8*x=1],[x]);
    (%o39) [[x = 1/8]]

    realonly:true;
    algsys([8*x=1],[x]);
    (%o41) []
