hi. i am not sure exactly what you are trying to do here. but you seem to
be using quite old instructions that relate to 'OE classic'. The wiki you
mentioned hasn't got any update from more than 2 years.

many changes have happened in OE, i suggest you start with
http://openembedded.org/wiki/OpenEmbedded-Core

you recipe as it is written wouldn't work with the OE-core, and guidelines
to migrate recipes can be found here:
http://openembedded.org/wiki/Migrating_metadata_to_OE-Core

i am not familiar with gumtix, but you might check with that community if
they release an OE  SDK you could use for cross compilation. or you can at
least get more up to date information about how to add your recipe in their
builds.
