Although, this is certainly an issue, one of the other things you may find
when compiling packages that use QT, is that your distro may place the files
in some location other than where the build files are looking for them.

For instance, on RH 7.x two version of QT are installed.  They can both 
be found under:

	/usr/lib/qt-1.45
	/usr/lib/qt-2.2.0

under each of these directories is a:

	lib
	include
	bin

directory.  In your case the package could not find the .h files.
Somehow you must make the package set the following parameter when 
compiling:

	-I /usr/lib/qt-2.2.0/include

This is of course assuming a RH system, with qt-2.2.0 installed.  Finally,
your going to get header file messages first, after they go away its 
probably going to fail in the link phase complaining about being unable
to find various .o files.  To fix this make sure when compiling the 
package uses the following switch:

	-L /usr/lib/qt-2.2.0/lib

With all that set you should be able to compile.
