Dear all,
I've been having problems running Sage 2.9 in my home computer: Athlon
XP 2800+, running Debian Etch, with kernel 2.6.18-4-k7.
I tried the pre-compiled versions, but they game many errors when
testing, which I assumed it was due to an old CPU (as I've seen
mentioned before). So, I compiled 2.9.3 from the source (which took a
long, long time, also as mentioned by someone else before).
Then, "make test" fails for "sage -t
devel/sage-main/sage/interfaces/sage0.py" (only).
Here is the error:

I am not sure what this affects, but many of my old computations still work.
Then I tried to check the new 3D plots. (It worked in my office
computer, and it looks great! Kudos!) When evaluating the Moebius
band sent by D. Joyner, I get a empty rectangle where the graph should
appear, and the lower left (status) bar of Firefox shows "Downloading
JmolApplet..." But nothing happens. Opening the Java Console (by
right clicking at the space for the plot), I get:

------------------
(Maybe related to the error from "make test" above??)
Any ideas?
Finally, (and this has been a "problem" for a long time, also in my
laptop, running Debian Etch again), I have jsMath fonts installed, but
sage (or Firefox) does not find it...
debian[~]$ wajig status jsmath
Package Installed Previous Now State
=======================-===============-===============-===============-=====
jsmath 3.3g-4 3.3g-4 3.3g-4 install
debian[~]$ wajig status jsmath-fonts
Package Installed Previous Now State
=======================-===============-===============-===============-=====
jsmath-fonts 1.3-1 1.3-1 1.3-1 install
debian[~]$ wajig status jsmath-fonts
jsmath-fonts jsmath-fonts-sprite
debian[~]$ wajig status jsmath-fonts-sprite
Package Installed Previous Now State
=======================-===============-===============-===============-=====
jsmath-fonts-sprite 1.0-1 1.0-1 1.0-1 install
I always get the "No jsMath TeX fonts found " box, and the fonts are
not as nice.
This is not a big deal, but it does look nicer when it works.
Any help would be appreciated.
Best to all,
Luis
