Do this:

```
sage -i http://www.sagemath.org/packages/experimental/cadabra-0.115.spkg
```

Or if you haven't downloaded it yet, just type "sage -i cadabra" and it should look up the version number and download the file.

I tryed, but:
make: *** No rule to make target 'all-toolchain'. Stop.
how to solve?

What version of Sage are you using? Did you download a binary version or source?

There's also "sage -f" (the "f" stands for "force"), which works just like "sage -i" but will install the spkg even if the same (or a later) version is already installed.

This is very useful when you're working on a spkg and making little changes, or if someone gives you a modified spkg with the same version.

And there is `sage -f -m` which installs the spkg and does *not* delete the build directory from `spkg/build`, which can be useful for debugging.
