Synaptic Touchpad installation

[.martin.]

I found the "Synaptic touchpad and usb mouse installation" guide in the forum, and thats what I still needed! But unfortunately, it didn't work out, just got a lot of error messages. I 'script'ed the output of

portupgrade -N synaptics

and these are just the first lines of each source of errors:

/usr/local/include/X11/os.h:110: error: syntax error before "va_list"
/usr/local/include/X11/os.h:260: error: syntax error before "va_list"
...
synproto.h:54: error: syntax error before "XISBuffer"
synproto.h:79: error: syntax error before "local"
...
synaptics.c:117: error: syntax error before "SynapticsPreInit"
synaptics.c:117: error: syntax error before "drv"
...
synaptics.c:1824: error: syntax error before "local"
synaptics.c:1826: error: `local' undeclared (first use in this function)

any hints?
