In GHC 6.4.2, the stage 2 compiler is built with -threaded, this is a 
change from previous versions.  If -threaded isn't working properly, 
then the stage 2 compiler will be affected - that seems to be the case 
on Solaris.

To get going, you could just disable -threaded in stage 2 (see 
ghc/compiler/Makefile).

Looks like 6.4.1 had some problems with -threaded on Solaris too.
