Since I didn't *really* try it with 1.5.11, but rather with a self-built DLL from CVS, you might try the latest snapshot and see if that fixes your problem. Otherwise, I had a WAG that it had to do with the presence of .exe in the symlink name and contents, but the guess didn't pan out for me -- it worked in all 4 combinations. I don't believe you ever said whether the *exact* sequence of commands below worked for you or not. Ah, another possibly relevant point: I use perl 5.8.2-1... Could you please try that?
