Hi Flinstone,
The cause does appear to be a bug, what version of LabVIEW are you on? I found a CAR (128114) which appears to be the problem where the bit file is storing an absolute path to the type def instead of a relative path.
Unfortunately this would either mean upgrading to 2012 or keeping the disk hierarchy in the same location on both machines. I guess a third option would be to disconnect the type definitions for the final build.
Cheers,
James
