Fatal error: Broken assembler - hello example

[Roogadget]

I've just setup my pulpissimo environment and when i run the hello example, I get the following:

This is also a problem for another person I work with:

internal error: can't hash `pv.add.h.div2': exists
Assembler messages:
Fatal error: Broken assembler.  No assembly attempted.
make: *** [/home/x/Documents/code/pulpissimo/sw/pulp-runtime/rules/pulpos/default_rules.mk:257: /home/x/Documents/code/pulpissimo/sw/pulp-runtime/hello/build/test/test.o] Error 1

I tired to switch to the v1 sdk but the error is still there.
