By just taking a look into the source I found in "ts_calibrate.c":
[...]
if( (tsdevice = getenv("TSLIB_TSDEVICE")) != NULL ) {
ts = ts_open(tsdevice,0);
} else {
ts = ts_open("/dev/input/event0", 0);
}
if (!ts) {
perror("ts_open"); <----- this spits out your error message
exit(1);
}
[...]
Seems you didn't define the "TSLIB_TSDEVICE" environment variable or it points
to nowhere.
