Did you just copy that file from master/dylan to danny? It wont work,
because it depends also on other changes, e.g.

http://git.openembedded.org/openembedded-core/commit/meta/classes/package.bbclass?id=5aa52c6882d2929b2e530c4fa297c6d3e97d4f9f

This version of that class is compatible with danny:
https://github.com/openwebos/meta-webos/commit/c5a3676e69ab54d62f29d7bbeb6a4ac517eb1c33

and this is the usage:
https://github.com/openwebos/meta-webos/commit/c9f91ecf31ebb602a8a86c8e2017ca431e2623e8

Yes you can do the same in recipe as what that bbclass does in more
generic way, depends on how many modules you need to fix..
