Hi,<br><br>when I install packages from cabal, the package manager installs already installed files (some of his favorites are process and haskell98)<br>so these packages are both system and user installed (that can cause later dependency problems, but the cabal FAQ explains very well how to recover from it)<br>
<br>but the funniest is that if I reinstall it, it again reinstall the same packages even they are already twice installed<br><br>does anyone know how to solve this issue?<br><br>Thanks<br>Louis<br>
