It's mostly painless to remove a package if:
-- you know where all its files are. Most of them are in
SAGE_ROOT/local/include/ and SAGE_ROOT/local/lib/ . It's pretty to
figure out what goes where from the spkg-install script.
-- you know that SAGE won't be using the functionality provided by
this package itself. It would be really cool if by removing maxima for
example, the uninstall script also figured out that that
SAGE_ROOT/devel/sage-main/sage/calculus/*.py would also have to be
removed. Really cool, but probably a bit overkill
-- you remove the file with its name located in SAGE_ROOT/spkg/installed/
BTW, I have attached a small patch that makes installing an SPKG from
a hard drive possible.

It's already there, along with all standard packages that are needed
to build SAGE. I'm not sure why it's still being downloaded.

There is a section on creating an SPKG
(http://modular.math.washington.edu/sage/doc/html/prog/node24.html), I
can update it to reflect the new changes.
