 The call to csc from the PATH is actually made by something in the
 qt.setup file. Here's the full compilation log (I've added {{{(run-verbose
 #t)}}} to the setup file):

 Warning: file does not exist: "qt.html"

   chmod a+r /usr/local/chicken-4.3.0/lib/chicken/4/qt.setup-info
 }}}

 Notice that there are calls to {{{`csc -libs -ldflags`}}} and {{{`csc
 -cflags`}}} which take csc from the system PATH.

 I supposed the following definitions from {{{qt.pro}}} cause this problem:

 {{{
 unix:QMAKE_LFLAGS_DEBUG+=`csc -libs -ldflags`
 unix:QMAKE_CFLAGS_DEBUG+=-w `csc -cflags`
 unix:QMAKE_CXXFLAGS_DEBUG+=-w `csc -cflags`
 }}}

 One solution I see is making qt.setup generate qt.pro.  A patch is
 attached.
