gnuplot 3.7, cant compile

Hi, I tried to compile gnuplot 3.7 on a debian machine runing debian 2.1r2. It gives lots of errors of the following type, on giving the command make gnuplot_x11. /usr/local/src/gnuplot-3.7/gplt_x11.c:1697: undefined reference to `XChangeProperty' /usr/local/src/gnuplot-3.7/gpl

Gnuplot 3.7

Anyone knows when/if gnuplot 3.7 will be avaliable as Debian package? Have a nice day,Paulo Henrique
