HaXml and ghc-current

Hi, I've just tried to install HaXml with the latest GHC from CVS, and the package compiles fine but the installation procedure aborts with: ghc-pkg: cannot find package HaXml `cat ghcpkgcmd` --add-package <pkg.conf Reading package info from stdin... ghc-pkg: Line 1: Invalid syntax (no colon after field name) Apparently something has changed in the package database format? I haven't been following all this, so I am a bit at a loss what to do. Has anyone else managed to install HaXml successfully? Any advice? Peter
