Thanks,<br>Alas adding '--constraint=hxt==9.0.\*' after cabal-install command does not help. I get the same error.<br><br><div class="gmail_quote">On Tue, Nov 8, 2011 at 2:10 PM, Erik Hesselink <span dir="ltr"><<a href="mailto:hesselink@gmail.com">hesselink@gmail.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">This is because hSimpleDB doesn't specify version ranges on its<br>
dependencies, when it should. Since hxt changed its module structure<br>
going from 9.0 to 9.1, hSimpleDB doesn't build against 9.0.<br>
<br>
You can try to build it by adding '--constraint=hxt==9.0.\*' after<br>
your cabal-install command. You can also ask the author to add version<br>
ranges to the package.<br>
