IDS11.70 developer edition on Ubuntu 11.04

I downloaded the Linux installation of CSDK 3.70UD3 and went to
install it on a known good installation of IDS11.70 and I get the
following. Any clues anyone? Is this a Locale issue?
Thanks

Hmmm. I uninstalled the CSDK V3.70UC3DE, tried CSDK V3.70UC3 with the same results so junked it and installed V3.50UD8 which installed correctly.
