Why didn't that occur to me? I should get more sleep. Thanks for the tip. Now I know that it definitely is SELinux, a system I understand not at all, I presume the problem is in these context things ... ghc has system_u and bin_t, while audley has unconfined_u and file_t. Time to go poking about. The unconfined_u looks suspicious. cheers, Fraser. On Tue, Dec 2, 2008 at 3:48 PM, David Leimbach wrote:

Hi all,

Has anybody seen this? I thought it might be an SELinux thing, but then I wouldn't expect GHC or darcs to run. Audley is a fairly simple program in operating system feature terms, but I get the same error with anything I build myself.

Thanks, Bulat, ticket #738 appears to be it. It was fixed in September, but I guess it hasn't made it to yum yet, although there's a work-around with permissions and so forth. cheers, Fraser. On Tue, Dec 2, 2008 at 4:42 PM, Bulat Ziganshin wrote:
