Dear all
I hit an error when building sage 4.7.0 on mac os x server 10.6.7 (on a mac=
mini, running in 64-bit kernel mode). I tried to build the package in a su=
bfolder of /Library. This specific location trigg
I thought about it and there is some hacked version floating around that
does this. But there are the following downsides:
* Any virtualization software needs superuser rights to install
* It would always conflict with a preexisting VirtualBox install
Really, you should install VirtualBox as
¿WOuld it be possible to modify slightly the virtualbox code to make
it run directly this virtual machine (without asking which one to run
and so on)? This would really be something very close to a one-click
install for windows.

No problem, your patch has double the speed. Details on the ticket.

Thanks, Dima, John, mmarco and Jason, for the very helpful comments.
Dima - had not thought about using QQbar! That pretty much gives the
output I would like to have as the default, other than the reference
to the "Algebraic Field" in the output. John sees my dilemma
exactly. The less I have to

As it's now the anniversary of the start of the move to having pari

I've updated my Sage virtual machine image. Now its as easy as it can be

I faced that kind of decissions when i implemented the eigen-stuff
for endomorphisms (see ticket 8974).
My opinion was to stick to the base field, and only look for
extensions when directly requested. David Loefler argued that, for
consistency reasons, it would be preferable to continue with the s
