[Haskell-beginners] rts package in an invalid state

Hi all, I recently compiled and installed ghc 6.10.2 on a clean system. But a 'ghc-pkg check' shows an error with the rts package [1]. A google search advised me to install libffi5. I did this but keep getting the same error. Any ideas? Thanks ... deech [1] http://hpaste.org/fastcgi/hpaste.fcgi/view?id=3630#a3630
