I also tried installing ghc-6.2 and had the same issues. Finally, I decided to rebuilding ghc-6.2.1 from source, and this solved everything:
- hmake 3.08 built cleanly from source (System.system worked) - compiled Haskell programs started processing their RTS flags again - my program that set an RTS hook doesn't crash on startup anymore
Given that, I think there isn't a bug in ghc per se, but rather a problem with the recent prebuilt glibc-2.2 ghc builds. I'm not sure what that might be, but I hope I've provided enough details to help isolate the issue (and please let me know if there are any additional details that would help).
Thanks,

Hello Ravi,
I recently have had a somewhat difficult time compiling and installing hmake-3.08 (from source) on a RedHat 7.2 system.
I have a RH7.2 system myself, and have now tried the combination of ghc-6.2.1 and hmake-3.08 there. You are right, System.system does not work correctly. Since it works fine with ghc-6.2.1 on newer OS releases (with glibc-2.3), this looks to me like a bug in ghc, and I have reported it as such. Hopefully it will be fixed in ghc-6.2.2.
Thanks for bringing it to our attention.
Regards, Malcolm
