Difficulties compiling hmake / HaXml

[Lescher Christian]

Now that I made it through the hmake compilation and went on to the haXml tools I come to another problem with compiling haXml.
The error message (below) lead me to the missing file (IOExts.hi) which I found in "/lib/imports/lang". I searched the Makefile and recognized the "HFLAGS" variable wich seems to be set for the ghc-compiler and the path to the "lang" directory.
But, as there is an error message what is wrong ? Is there a problem with the Makefile or the directory structure? Can you help me go on?

Cheers, Christian
