&gt; cabal update<br>
&gt; cabal install cabal-install<br>
&gt; cabal install cabal-dev<br>
The last command fails with:<br>
Resolving dependencies...<br>
In order, the following would be installed:<br>
tar- (new package)<br>
transformers- (new version)<br>
mtl- (new version)<br>
parsec-3.1.3 (reinstall) changes: mtl-2.1.2 -&gt;<br>
network- (new version)<br>
HTTP-4000.2.8 (new version)<br>
cabal-dev-0.9.1 (new package)<br>
cabal: The following packages are likely to be broken by the reinstalls:<br=
Use --force-reinstalls if you want to install anyway.<br>
I *think* the problem is that cabal-dev has these dependencies:<br>
=A0 =A0 =A0 mtl &gt;=3D 1.1 &amp;&amp; &lt; 2.1,<br>
=A0 =A0 =A0 transformers &gt;=3D 0.2 &amp;&amp; &lt; 0.3,<br>
where the latest version of mtl and transformers are 2.1.2 and 0.3 respecti=
vely. At least, if I download the latest cabal-dev package and relax those =
upper bounds I can get it to install.<br>
The irony is, of course, that I&#39;m trying to install cabal-dev to get me=
 out of a totally unrelated dependencies hole!<br>
What should I do now?<br>
