GTK Theme Preferences is available in the Shimmer Project PPA for Ubuntu 12.04 Precise Pangolin and 12.10 Quantal Quetzal. Add the PPA and install it using the following commands:
sudo add-apt-repository ppa:shimmerproject/ppa sudo apt-get update sudo apt-get install gtk-theme-config
The commands are for Linux system and I have a FreeBSD System . So my question is how can I istall on FreeBSD ?
