compile error

[LiNuts]

i have installed kde3, and now i am trying to install koffice-1.2, but during the ./configure i am getting this error.
'checking for libz... configure: error: not found'
I had a look, and i have libz.so.1 installed in /usr/lib/libz.so.1
How do i point the configure to look for libz in /usr/lib/, i checked in the config.h.in file but there is nothing ablout libz.
Cheers

Check to see if you have the development stuff installed. This is usually the problem when configure can't detect a library.

I installed libz1g-dev and reran the config, got past that point, then it couldn;t find libjpeg, so i installed the dev package for that, reran config, then it couldn;t find qt3, so i installed libqt3-dev, reran config, now its asking if i compiled qt3 with threads (??). Any idea of what i should install next.
