Hi Qi,
when you followed the instructions from my tutorial did you also follow the following part?
"When the DB2 Setup Wizard prompts you for the type of installation requested, ensure that you select “custom” and then, when prompted with the “Features” screen a couple of clicks later, select “Base application development tools” under the section “Application Development Tools” (the check box should switch from gray to white and be marked off)."

Hello there.
From the error messages you aren't finding the DB2 libraries and header files you need.
What Linux distro are you running ?
How did you install DB2 : via db2setup (graphical) or db2install (non-graphical) ?
Did you create the instance as part of the install or later ?
It may be that you want to try creating the links again by running (as root) -
/opt/ibm/db2/V9.5/cfg/db2ln
Then try again.
HTH
