New description:
If you want to try the code out do this:
1. Install sage-3.4.2.
2. Build pynac (should take about 3-5 minutes):
{{{
./sage -i
http://sage.math.washington.edu/home/mhansen/symbolics/pynac-0.1.6-mh.spkg
}}}
3. Apply the two patches at
http://sage.math.washington.edu/home/mhansen/symbolics/
{{{
sage:
hg_sage.apply('http://sage.math.washington.edu/home/mhansen/symbolics/symbolics_1.patch')
sage:
hg_sage.apply('http://sage.math.washington.edu/home/mhansen/symbolics/symbolics_2.patch')
}}}
Just check in each with some random comment.
4. Delete all traces of constants.so:
{{{
rm devel/sage/build/*/sage/symbolic/constants*
rm devel/sage/build/sage/symbolic/constants.so
}}}
5. Build with "sage -br", and it should work. Building will take a while,
since the patches touch many files.
