The tool DAVID is included at the public Galaxy Main server http://usegalaxy.org and is in the Tool shed http://usegalaxy.org/toolshed (from where it can be installed into a local/cloud Galaxy). At Galaxy Main, it is organized under the tool group Phenotype Association.
Other metagenomic tools do this type of association are in the tool group Metagenomic Analysis. These require a different type of input. I wanted to mention that in case you haven't settled on a method or want to compare methods.
The tool that previously derived this information from Megablast output is no longer supported at Galaxy Main, but it is in the Tool Shed (here). Be aware that the set up will take some time due to the size of reference files used, and that you might need to remap against the same version of ht/htgs as NCBI is currently publishing taxonomy data for.
Hopefully one of these options works out for you, Jen, Galaxy team
