osprey buildfarm member has been failing for a long while

"osprey" hasn't been able to build HEAD since the GIN code was added.
I'm not sure that GIN is really to blame though, as the error looks
like an out-of-memory problem while trying to link the backend:

gmake[2]: *** [postgres] Error 1

Perhaps the swap space or ulimit setting on the box needs to be raised?
