TBB package different for 32bit vs. 64bit in rawhide?

[Richard Shaw]

I'm having trouble building a package that uses TBB, but only the
32bit builds are failing with this error:

libOpenImageIO.so.1.0.0: undefined reference to `__TBB_machine_store8_slow'

Any ideas? For now I'm %ifarch'ing around the problem.

Thanks,
Richard
