Dear Johannes,
How did you install? From the PPA? Is this the sagemath-optional trying to build?
Note that this package might be discontinued in future as I see this message:
"Installing optional GAP packages, which may not be open source."
and free PPAs are only for open source. It's also not well designed, it currently
builds packages as root, which is bad practice and dangerous to your system;
but that can be fixed.
For others: sagemath-optional currently installs these:
0 jan@osprey:~$ls /usr/lib/sagemath/spkg/optional/
biopython-1.60.spkg database_odlyzko_zeta.spkg
database_cremona_ellcurve-20120827.spkg database_sloane_oeis-2005-12.spkg
database_gap-4.4.12.p1.spkg database_symbolic_data-20070206.spkg
database_jones_numfield-v4.spkg dot2tex-2.8.7-2.spkg
database_kohel-20060803.spkg gap_packages-4.4.12.p1.spkg
Johannes, please list the installed PPA packages:
dpkg -l |grep sagemath
This package compiled for me on an up-to-date 64bit system. Your sage can work
perfectly without sagemath-optional, which is not yet a reliable package. You can remove
it with
sudo apt-get purge sagemath-optional
But if you want to help test, and understand the risks, can you do this
sudo apt-get update
sudo apt-get dist-upgrade
sudo sage -f /usr/lib/sagemath/spkg/optional/gap_packages-4.4.12.p1.spkg
Regards,
Jan
