Hello,

help me?

What do you mean with this? I don't understand the process... When I execute
"install.sh", I usually get a "ln -s xxx yyy" failed because yyy already
existed, so I delete all yyy*'s and then reinstall. Is that correct?
Should I:
1: scons --clean
2: scons
3: install.sh $ONE_LOCATION
or what?

Also recompiling makes executables in the installation directory updated.
