Hi there. I'm running Backtrack 4 R2 (kernel 2.6.35.8), and I've run into a "show stopper" during installation of gpredict-1.3:

configure: error: Your intltool is too old. You need intltool 0.21 or later.
I've come across some history for this error: http://old.nabble.com/Bug-555953%3A-FTBFS%3A-.-configure%3A-line-3720%3A-intltool-update%3A-command-not-found-td26326148.html
It appears you do not have the developers packages installed to allow compiling.
The link you provided showed another package was needed for compiling cleanly. I am not familiar with your distribution to recommend the packages you need.
I looked into this further, apt-get install intltool will get you over this hump. However the gtk+, glib, gthread, goocanvas, and curl libraries are all too old for gpredict 1,3.
You might want to look at an earlier version,
