If you're running across this issue somewhat after the fact (as I did), it appears that it has been fixed in a later release of the SSDT-BI tools installer. Either that, or the process of re-installing fixed it for me.

The file name of the installer on the download page has not changed, but there was a new version released in March of 2015. The new version number is 11.0.5583.0, and the previous version that was causing this error was 11.0.3436.0.

So a simple update might be sufficient. It worked for me with no changes to the GAC.
