No offense :-) Thanks for taking the time to investigate this stuff. It gave me the opportunity to get a closer look at ghc package management.<br><br>Regards,<br>Arnaud<br><br><div class="gmail_quote">On Mon, Aug 29, 2011 at 5:28 PM, Albert Y. C.

I am sorry. I apologize. It was not your fault. It was my fault. &quot;unregister --user&quot; drops the global instance when there is no user instance, which is when the 2nd time you issued the command. It is a ghc-pkg bug.<br>

<br>
(I already knew the dual bug: &quot;unregister --global&quot; drops the user instance when there is one. I make do with &quot;unregister --global --no-user-package-conf&quot;.)<div><div></div><div class="h5"><br>
