为什么不能动态构建mighttpd2？

当静态链接我的可执行文件时，GHC速度太慢，所以我想使用“-dynamic”选项进行测试。尽管cabal install mighttpd2没问题，但以下两个命令会导致相同的错误。为什么不能动态构建mighttpd2？

$cabal install --ghc-options=-dynamic mighttpd2 
$cabal install --enable-executable-dynamic mighttpd2 

Linking dist/build/mkindex/mkindex ... 
Preprocessing executable 'mightyctl' for mighttpd2-2.7.1... 
Process.hs:11:8: 
    Could not find module `Data.Conduit.Process' 
    Perhaps you haven't installed the "dyn" libraries for package `process conduit-0.5.0.2'? 
    Use Perhaps you haven't installed the "dyn" libraries for package `process-conduit-0.5.0.2'?

您需要安装mighttpd2所依赖的所有库的动态版本。 cabal-install正确地抱怨process-conduit的动态版本不可用。您必须重新安装mighttpd2的整个依赖关系树，并将--enable-shared --enable-executable-dynamic传递给cabal-install。

谢谢！但如何使用cabal重新安装mighttpd2的整个依赖树？ –
