1. problem during install

>>export: 137: 3000.00: bad variable name

2. found a fix at Alter forum(root cause: dual core freq)

modify the following file, line 147

/altera/10.1/quartus/adm/qenv.sh

original:export QTB_CPU_FREQ=`cat /proc/cpuinfo | grep "cpu MHz" | cut -c 12-18 | uniq`

fix: export QTB_CPU_FREQ=`cat /proc/cpuinfo | grep "cpu MHz" | cut -c 12-18 | head -1`

3. install device package

altera/10.1/quartus/bin/quartus_sh  --qinstall -qda "10.1_quartus_free_linux/altera_installer/bin/../../devices/subscription/XXXX.qda" -show_qt_progress

## XXXX.qda, check uncompressed directory "device"
