compiling PrimOp.lhs

Dear GHC developers,

`Making' GHC of   cvs update -r ghc-6-2-branch

with  ghc-6.2.1 

on  RedHat Linux (about version 8) libc-2.2, i686

seems to meet a problem:

  -- OK, probably  make boot  not needed,   right?

  > make all

Now, it stayed at this point for about 50 minutes, no messages appear,

I have just interrupted it.

What is the matter, please?
