Impossible happens compiling darcs

When I compile darcs with profiling (doing "./configure --disable-threaded --enable-profiling"), I get:

rm -f Main.hi Main.o
[ghc] stringify
PATH=".:$PATH" darcs changes --context | cat config.command - \
                | ./stringify Context context > \src/Context.hs

darcs failed:  Not a repository
