DevOps, CI/CD and Automation

I installed Sun studio11 successfully in Sun blade 1000, located in /opt/studio/;
And I want to so some changes in /usr/ccs/bin,

ln -s /opt/studio/SUNWspro/prod/bin/acc ucbcc
ln -s /opt/studio/SUNWspro/prod/bin/lint ucblint
ln -s /opt/studio/SUNWspro/prod/bin/whatdir whatdir
I also checked the files in this directory, there are 103 files in it.

But there is no "acc" in /opt/studio/SUNWspro/prod/bin/, may be some package about it hasn't been installed?
Is someone know which patch missing or provide some help on it?
Very appreciate!
