sandbox and mysql 5.5? (no replies)

Hi folks, I'm trying to install MySQL-5.5, using the mysql sandbox, but..apparently the tar balls being generated no longer play nice with the sandbox..

When I run:
make_sandbox MySQL-5.5.17-1.linux2.6.x86_64.tar
I get:

The MySQL Sandbox, version 3.0.21

********************************************************************************
Not a tarball (/home/dhopkins/sandboxes/MySQL-5.5.17-1.linux2.6.x86_64.tar).
Accepted paramethers are: {VERSION|tarball_full_name} [options].
********************************************************************************
usage: ./make_sandbox version [options] {VERSION|tarball_full_name} -- [more options]

--export_binaries exports the new binary to /home/dhopkins/opt/mysql
--add_prefix=NAME add given prefix to renamed tarball directory

Additionally, you can pass any option accepted by "low_level_make_sandbox" after '--'
You should provide either a version from '/home/dhopkins/opt/mysql'
or an absolute path to the tarball to extract.
See (below) ./low_level_make_sandbox --help for more detail
version should be provided as #.#.#


any thoughts? pointers?
