That explains the warning, though not why ld is looking for that 
directory. Since I don't know Macs, I can only guess.
Maybe the fact that you untarred ghc to 
/Users/me/my_tar_extractions/ghc-6.8.2 confused it as it expected to 
be untarred to /usr/local/ghc-6.8.2 and find the frameworks in 
../../Library/Frameworks.

You can try symlinking /Library to /Users/me and see if that gets rid of 
the warning, though for a real fix, a mac-user's answer would be 
required.
