Comment(by was):
wjp figured out that this boils down to some tuning program not getting
built:
{{{
sage subshell$ gcc -fPIC -std=c99 -O3 -L.
-I/home/wstein/screen/eno/sage-4.4/local/include -I./include -DNDEBUG -o
tune/mulmid-tune.o -c tune/mulmid-tune.c

sage subshell$
}}}
For this,
{{{
14:26 < wjp> the fix is to move the lines
14:26 < wjp> const int max_intervals = 20;
14:26 < wjp> size_t points[max_intervals + 1];
14:26 < wjp> double score[max_intervals + 1];
14:26 < wjp> up a bit to at least above the goto
}}}
but...
{{{
4:26 < wjp> but after doing that it is now complaining about a missing
ZNP_tuning_info when linking 'tune'
}}}
