hmake -hat looks for file in /usr/include, not PWD

"hmake -hat -package GLUT Main" fails with:
"Fail:
/usr/include/hat/DoublyLinked.hx: openFile: does not exist
(No such
file or directory)".  DoublyLinked.hs is sitting right
in the
directory from which I'm compiling, I'm not sure why the
-hat flag
causes this digging in /usr/include.  Deleting
"-hat" causes
successful compilation.

The directory tree looks like this:
lanes/
ByKey.hs  DoublyLinked.hs  IfPrime.hs  Main.hs  MaybeBool.hs
Traffic.hs Traffic/
lanes/Traffic/
Data.hs  Sim.hs  Units.hs

This is hat 2.02-12 and hmake-3.09-3 on Debian stable x86.

This is the full text of the build:

You are using an older version of Hat, so this behaviour may
have been
fixed already in 2.04.  I'm not sure quite why it is
failing.  But one
possible workaround is to explicitly give the current
directory to hmake,
as a location to look for the .hx pseudo-interface files. 
(Use -i.)

    hmake -hat -i. -package GLUT Main

I'm reasonably confident that this hasn't been fixed even in
the cvs  
build - I've met the problem a couple of times before, and
never  
found a good reason for it to happen (I don't know anything
about how  
hmake works)

Hm... the problem persists on a machine with:

hat/dapper  2.04-0ubuntu2
hat-ghc6/dapper 2.04-0ubuntu2
hmake/dapper 3.10-1.1

Also, "-i" doesn't work around, for some reason.


Other than hopengl, this project is basically
self-contained, if
anyone's interested in trying to reproduce this, take a look
