Kacpi error: Qt (>= Qt 3.0.3) (library qt-mt) not found

["suresh Sharma" <surri2003@rediffmail.com>]

hi,
I have a debian testing on my sony vaio laptop .
I have acpi support in my kernel verion 2.4.20 ( ACPI patch ) .
I was trying to install Kacpi from source but
when I do ./configure I keep getting error
this error .
"checking for Qt... configure: error: Qt (>= Qt 3.0.3)
(library qt-mt) not found. Please check your
installation!"

I checked what version of libqt-mt-dev I have and it
is 3.0.5
I did dpkg -l | grep libqt
ii  libqt2         2.3.2-5        Qt GUI Library
(runtime version)
ii  libqt2-mt      2.3.2-5        Qt GUI Library
(runtime threaded version)
ii  libqt3         3.0.5-3        Qt GUI Library
(runtime files)
ii  libqt3-dev     3.0.5-3        Qt GUI development
files
ii  libqt3-mt      3.0.5-3        Qt GUI Library
(Threaded runtime version)
ii  libqt3-mt-dev  3.0.5-3        Qt Threaded
development files

so why is it still complaining
help !!
I relatively new to this linux world so pls bear with
me .

thanks
