If you install a package through cabal install, it will automatically register with GHC (it works the same way that gems works on ruby for example)<div><br></div><div>Using runhaskell <commands> is whats used when manually building/configuring packages (for example creating archlinux packages from cabal packages from hackage) or when you are developing and creating cabal packages yourself</div>
<div><br></div><div>(in other words, when you do cabal install, cabal internally does all the commands for configuring/checking dependencies/building and installing)</div><div><br></div><div>So you should be able to use use the package instantly after you install it (you can also use ghc-pkg list to check all installed packages)<br>

Hi everyone,<br>I have installed ghc 6.12.3 and the Haskell platform; now, when I install<br>packages from hackage using<br> cabal install <package-name>,<br>they get installed in ~/.cabal,<br>which is fair enough.<br>
However, when I call a <br> runhaskell Setup.lhs configure <br>that used to work on a different computer with the same software setup,<br>ghc (or is it cabal?) complains that it cannot find the packages I have just installed.<br>
Checking again revealed that they are indeed installed, just not in the ghc installation directory,<br>but under ~/.cabal.<br>How can I tell cabal and/or ghc where to look for libraries?<br><br>Thanks, again, for any help!<br>
