ation, it would be better to do a fresh install using the bootstrapped GHC =
you can find on the website. Roughly I have done this way (on my Mac and on=
 My EC2 instance):<div>
<br></div><div>(inside a ghc bootstrapped folder)</div><div>./configure --p=
refix=3D~/Library/Haskell/ghc-xxx (where xxx is the version)</div><div>make=
 install</div><div><br></div><div>(then inside ~/Library/Haskell)</div><div=
ln -s ghc-xxx current</div><div>ln -s current/bin bin</div><div><br></div><=
div>This way my current GHC is pointing to current inside ~/Library/Haskell=
/current and my bin are updated accordingly (make sure to add /bin to your =
$PATH!). Then you install cabal-install and you are pretty much sorted. The=
 advantage of this approach is that you have the control over the installat=
ion process, but other suggestion (like Alp&#39;s one) are pretty good too.=
 Mostly depends on what you think will work best for you :)</div>

I have Haskell Platform with GHC[i] 7.4.2 installed on a MacOS system. =C2=
=A0There&#39;s a problem with the handling of certain Markdown constructs i=
n literate Haskell (lines starting with &#39;#&#39;) that I understand is f=

Therefore, I&#39;d like to be able to update my GHC installation to 7.6.2. =

 upgrade an existing GHC installation. =C2=A0Am I missing something?<br>
