Do you mean postBuild instead of postConf?

Yes, this is pretty weird. Can you strace?

However, working or not, this is wrong, you should not create the manpage in
the source tree. Instead, you need to create it somewhere under
dist/... Moreover, hardcoding "dist" is not the best idea ever either. See this
code in runTests:
cwd <- getCurrentDirectory
let abs = isAbsolute $ buildDir lbi
path = (if abs then id else (cwd </>))
(buildDir lbi </> "darcs")
You could probably factor that out and use it in your code as well (or maybe
something like this is already hidden in Cabal somewhere, I just haven't found
it.)
Yours,
Petr.
