Yep. This is due to differences between the installed glibc on the two  
systems; the Haskell runtime uses the appropriate timer_create code  
(necessary for threading) for the system it was built for, on other  
systems you can get the above error.  I see this a lot with local  
supported ghc builds, especially when trying to bootstrap from an  
existing binary.

All you can realistically do is relink the program on each system,  
which must have the appropriate compatible ghc runtime installed  
already.
