Hello,<br><br>&nbsp;&nbsp;&nbsp; I trying to get a library to build ... I am following&nbsp; the instructions&nbsp; in <a href="http://en.wikibooks.org/wiki/Haskell/Packaging">http://en.wikibooks.org/wiki/Haskell/Packaging</a>. Under&nbsp; the &quot;Build your project&quot; section in this web page, when I try to do an actual build (runhaskell 
Setup.lhs build), the imported module System.Environment cannot be found. I suspect that there is a &quot;cygwin&quot; (&quot;Linux/Posix&quot;) environment variable that needs to be set to point to the Haskell libraries/packages. ??
<br><br>Kind regards, Vasya<br>
