Semaphore library error on L4Env/Fiasco-UX

using the current CVS version of Fiasco and L4Env I get the following 
error on startup of the system with Fiasco-UX:
exec    | Startup: semaphore lib initialization failed (-1)!

The task on which it fails varies depending on which startup script from 
l4/tool/runux is executed but it's always the first or second task that 
L4Env is compiled with gcc-3.3.6 and Fiasco with gcc-4.0.2.

Is this a known problem?
