Permissions error on local installation

I have a site running quite happily on a live server.

I'm now trying re-create it locally in order to test some changes. I've taken an SQL dump from live and setup a database using same DB user data as live (per config file).

When I try to access the site I get a directory permission error:
Warning: mkdir(): Permission denied in <snip>/frozenbanana/gallery2/modules/core/classes/GalleryPlatform.class on line 582

This is presumably just a Linux and/or Apache permissions thing. The pages not using gallery can be rendered correctly.

Anyone willing to hazard a guess what directory this might be that is not creatable?
I've compared my gallery temp/data directory and it seems to have the same structure as my live site - I even tried changing the whole project to 777 but I still get this permissions error.

I'm guessing it's something about trying to compile styles/templates but I can't remember where this stuff lives (ie where it's trying write to).

Gallery is running in embedded mode if that matters.
