`port info ghc reported that it was _not_ revision 2 and so I did the 
`selfupdate' as advised. this went OK. I then did

sudo port upgrade ghc

but this did not go so well:

after some fetching/compiling it crashed and a second try yielded:

--->  Activating ghc 6.4.2_0+darwin_8

as in the first attempted `upgrade' the problem seemed to be the 
unability to fetch readline51-001 from any site.

what is a poor guy to do? where is(are) my fault(s)? up to now I've been 
'fully elastically reflected' by ghc :-(

all the best
