TYPO3 Core

I've just installed a fresh copy of typo3-4.0rc1pre1.
Then I've installed dbal and adodb, no further configuration.
Then I want to install the newest snapshot of dam "20060228". I recieve the following error message:

ERROR: Query could not be parsed: "SQL engine parse ERROR: Field type unknown in parseFieldDef()!: near "float unsigned default '0', height float unsigned "".

When I uninstall dbal the installation work fine.
