Compiling X4.0.2

[Cameron Matheson]

Hey,   I just compiled X4, but after I did "make install >& install.log" I checked the log, and it bailed because I don't have "-lz".  What package is this library in?  (or where can I download it?).  Also, I'm trying to install emacs, X, etc.  Someone told me I could if I put the packages on hold, but it still won't let me install without install xfree86-common/xlib6g.  Please help me.   Thanks, Cameron Matheson
