[TxMt] [TM2] Git bundle complains about missing TM_SUPPORT_PATH?

Trying to get to grips with TM2...

Using any command from the git bundle I get this alert panel:

Failure running “Show Uncommitted Changes”.

Fail whale detected!

TM_SUPPORT_PATH is not set. This is probably because you are running specs from outside of TextMate.

You can set TM_SUPPORT_PATH using something like...

export TM_SUPPORT_PATH='/Applications/TextMate.app/Contents/SharedSupport/Support'

I checked the recent posts but can't find a solution. Amy suggestions?

Also while the file browser sidebar does show the SCM status (eg the circle for files with changes), the "purple folder" icon does not do anything for me. Did that break in 8949?

Thanks
