Package Main

I'm running into a strange problem when I build the X11 library using current 
ghc (built from repository yesterday using gcc 3.2).  The error message I get 
is:

   ghc-6.1: unknown package name: Main

The puzzling bit here is that I am compiling a part of a library using -c, I 
don't mention a package called Main and package.conf doesn't mention the word 
Main.  So why does the error message mention Main?

Any thoughts?

ps The command is

/usr/local/bin/ghc -H16m -O -Wall -cpp -fglasgow-exts -fffi -Iinclude -package 
haskell98 -package HSgreencard -package-name HSX11 -O -Rghc-timing  -package 
haskell98  -package HSgreencard -split-objs    -c Graphics/X11/Types.hs -o 
Graphics/X11/Types.o  -ohi Graphics/X11/Types.hi -v 2> /tmp/log2 1> /tmp/log1

and I'm including Types.hs, stdout and stderr as attachments
