Error in make with Tslib

[jsprankle at awlship.com]

Using xorg-server-1.5.3 builds fine with 
 --enable-kdrive

if I use 
 --enable-kdrive --enable-tslib i get the following error when I run make

Error
Making install in vesa
make[3]: Entering directory `/home/joe/Desktop/xorg-server-1.5.3/hw/kdrive/vesa'

I installed tslib from source with the generic build instructions from http://tslib.berlios.de/

Any suggestions on what I'm missing?
