Sorry, I thought there is only one way to install Sage packages.
I ran sage -i dot2tex.
The error log is attached to my previous mail.

Hi!
I tried install dot2tex in Sage 8.1 and got error building mpfr. See the
attached log. At first it actually failed with complaints about mpfr being
too old (version 3.8 or something) so I did
./sage --package update mpfr 4.0.1 --url

Hey Travis,
thank you for clarification.

The ticket https://trac.sagemath.org/ticket/14779 seems to be related.

If you try to test for equality in a finitely presented groupy the sage
kernel can crash.
The following real life example leads to restarted kernel in the notebook
interface and to "gap: cannot extend the workspace any more!" in Sage
terminal interface (and nongraceful exit).
k = 3
p = 18

Hi!
I am trying to work on #15948 and the last change bumped the code from 6.1 to
6.2-beta5. I tried ./sage -b, make and ./sage -f libgap but I still get the

An error occurred, but libGAP has no handler set

Hi!
I am working on ticket #15272 and the branch I've created is red, there's
no cummulative patch and mouseover information says trac's automerging
failed
What is wrong and how do I fix it?
Also the patch is basically finished and the only missing things are some
doctests. Could somebody

I am working on extending (non-affine) DynkinDiagrams so they allow
arbitrary labels over the nodes as well as different type of nodes (i.e.
crosses). The purpose is using sage for producing examples to be included
in papers. See e.g. http://arxiv.org/abs/1303.1307 page 36. I haven't

an automorphism of the Dynkin diagram, so it must be nontrivial when the
Dynkin diagram has no automorphism. But if there is a

I'll post patches as soon as I get properly acquainted with sage patch

Just in case, I'd rather avoid this assumption if you can.

Sorry for spamming the list. It seems that I will have to wait for the trac
account for quit a while. Please feel free to try out the attached patch.
