Qsys 11.0sp1 DDR2 Uniphy generation problems under suse

I am using Quartus 11.0sp1 on Suse linux 11.4 (64bit), and try to generate a

simple system with a nios processor, onchip memory and a ddr2 Uniphy

controller in Qsys.

The system generation works fine on a windows system but under linux I get the following error message:

# #######

Does anybody have any hints?

Thanks
