Hi,<br><br>I pulled jhc sources (jhc, doc, haskell98, QuickCheck) from darcs and tried building jhc. But the build exits with the following error: <br><br>jhc$ make<br>ghc -O -ignore-package lang&nbsp; -pgmF drift-ghc&nbsp; -F -W -fno-warn-unused-matches&nbsp; -i. -iFrontEnd -package mtl&nbsp; -package unix -package QuickCheck -fwarn-type-defaults&nbsp;&nbsp; -fallow-undecidable-instances&nbsp; -fglasgow-exts -fallow-overlapping-instances&nbsp; --make
