No, the root process is different.
With GB, one boots into Amon RA recovery, and there is a menu item to install Superuser app and its Su file. Problem is that with HTC ics even the latest release candidate beta of Superuser will not work properly.
With HTC ics, download from xda developers the competing app SuperSU and flash it using Ramon RA recovery.
The file you need to download is called CWM-SuperSU-v0.93.zip
If you have Superuser installed, uninstall it before installing SuperSu. Also the su file that comes with these apps are different and incompatible.
After SuperSU is installed, download from google playstore the BusyBoxInstaller app by JRummy, run it to install the latest version of busybox. Many rooted apps needs busybox to operate.
