yeah, come to think of it, it is probably that i changed some things
without doing clone first (in my defense clone eats up a lot of space
on small hdd).
Fortunately it eats up less now, as the build output, .c files, and (I
think) docs are hard linked rather than copied, though it's still non-
trivial.
here is the hg heads output. Not sure how it is supposed to look, but
probably having two heads is unusual?
Yes, at least the way we do things.

summary: 4.3
This means that you're sage library really isn't really upgraded to
4.3. (In some sense, 4.3 is sitting in a branch parallel to your
modified one). You're actually lucky it broke as cleanly as it did--
sometimes upgrading all the spkgs without upgrading the core library
can cause hard crashes or strange behavior.
There was talk of changing the upgrade script to fail more gracefully,
see
http://groups.google.com/group/sage-devel/browse_thread/thread/5b566397731862d/166786f3ecf855ca?lnk=gst&q=expert_upgrade#166786f3ecf855ca
No one got around to actually doing it though.
Thanks for the help probably will do a fresh reinstall. If i keep
braking Sage maybe I would learn the basics of software development
soon.
Easier and faster than a whole new install, what you can do is move
your sage-main to, say, sage-main-old, then do
sage -f $SAGE_ROOT/spkg/standard/sage-4.3.spkg
Which will create a pristine sage-main for you. I would recommend
always working in a clone, typically you'll only ever need one. Queues
make life a lot easier too.
